Transcript 0:00 · as you watch this swaths of the 0:01 · astronomy Community are engaged in the 0:03 · greatest treasure hunt in over a century 0:06 · somewhere out on the fringes of the 0:08 · solar system it's thought a massive 0:10 · object might L one we've so far only 0:12 · been able to indirectly sense thanks to 0:14 · its gravitational effect on several 0:16 · smaller objects but which may soon be 0:18 · cited directly a here to unnoticed 0:20 · planet that would represent the First 0:21 · new addition to our Cosmic Family in 0:23 · living memory known imaginatively as 0:26 · Planet 9 this invisible world is 0:28 · currently only theoretical but since it 0:30 · was first proposed in 2016 evidence has 0:32 · been stacking up that it may be out 0:34 · there evidence that suggests we might 0:36 · soon have to rewrite the entire history 0:39 · of the solar system I mean at least 0:41 · that's the hope the plane sized pot of 0:43 · gold tempting astronomers to keep 0:45 · following this Cosmic rainbow yet as 0:47 · we're about to see the science 0:49 · surrounding Planet 9 remains unsettled 0:52 · it could be Humanity's next great 0:53 · discovery or it could be something far 0:55 · weirder join us today as we turn our 0:58 · attention to the edges of our solar 0:59 · system and try and separate fact from 1:01 · fiction regarding our missing neighbor 1:03 · ironically the idea of a missing ninth 1:05 · planet was born at the exact same moment 1:07 · astronomers were reducing the official 1:09 · tally down to eight the era was the 1:11 · beginning of the 21st century an era 1:14 · that had seen a Cascade of discoveries 1:16 · about the outer solar system along with 1:18 · major controversy first the discoveries 1:20 · back in 1992 scientists have finally 1:22 · confirmed the existence of the Kyper 1:24 · belt a ring of objects beyond the orbit 1:27 · of Neptune filled with icy bodies but it 1:29 · was only as the new century dawned that 1:32 · the size of some of these bodies started 1:34 · to become clear between 2002 and 2005 1:37 · researchers led by Mike Brown cited six 1:39 · dwarf planets that rivaled Pluto it was 1:41 · this last fact that sparked controversy 1:44 · with one of the Newfound dwarf planets 1:46 · arys having a greater mass than the 1:47 · former ninth planet astronomers began to 1:50 · question whether poor old Pluto is even 1:53 · really a planet at all infamously this 1:55 · led to a 2006 meeting of the 1:57 · international astronomical Union where 1:59 · attendees narrowly voted to strip Pluto 2:01 · of its status yet even as kids 2:03 · everywhere began unhappily redesigning 2:05 · their science fair solar system models 2:07 · there were already signs emerging that 2:08 · there might be a ninth planet after all 2:10 · that while Pluto may be too small to 2:12 · really count that didn't mean there 2:14 · wasn't another larger World lurking out 2:16 · there the first clue came from one of 2:18 · the new dwarf planet candidates sedna 2:21 · Unlike Pluto arys or other newcomers 2:24 · like maam Mara or how mayor sedna didn't 2:26 · behave like a regular Kyper belt object 2:29 · instead it had an extremely weird orbit 2:32 · one that took it from a closest approach 2:34 · to the sun of 84 Au where 1 Au is the 2:37 · distance from Earth to our star all the 2:39 · way out to a furthest point of 937 Au a 2:43 · bizarre elongated orbit that takes over 2:45 · 11,000 years at the time it was assumed 2:48 · that SED was simply a weird one off a 2:50 · freaky little world doing its own freaky 2:52 · thing on the outskirts of the solar 2:53 · system but then we began to locate and 2:55 · investigate more and more objects in the 2:57 · region and it started to look like maybe 2:59 · set no wasn't alone trans neptunian 3:01 · objects or tnos is the name given to 3:04 · small icy bodies just beyond the orbit 3:06 · of Neptune leftover building blocks of 3:08 · the solar system they're often quite 3:10 · hard to detect although we think tnos 3:12 · larger than 100 kilm May number in the 3:14 · hundreds of thousands so far we've only 3:16 · located about 4,000 of them but even 3:18 · with this small sample size we can see 3:20 · that some of them behave in ways our 3:22 · model of the solar system doesn't 3:23 · predict first there are the detached 3:26 · tnos accounting for about 10% of all 3:28 · tnos the these little dudes have orbits 3:31 · that aren't influenced by Neptune while 3:33 · a models say a few should exist it's 3:35 · very hard to account for the sheer 3:37 · number of them next you have a bunch of 3:38 · TNS with orbits at Wild angles that 3:41 · means they zip around the Sun at a tilt 3:42 · of more than 45° another thing our 3:44 · models don't predict happening on such a 3:46 · large scale finally there are the tnos 3:49 · with such odd orbits that they're 3:51 · sometimes dubbed etnos extreme trans 3:54 · neptunian objects numbering about a 3:56 · dozen they're scattered in such a wild 3:58 · way that some new gravitational s ources 4:00 · seemingly needed something that threw 4:02 · them out of alignment in the distant 4:03 · past and now keeps them trapped in their 4:06 · eccentric dances the CTIC astronomers 4:08 · Mike Brown and Constantine batan there 4:10 · was one simple explanation in 2016 they 4:14 · published a paper suggesting sedna and 4:16 · five other etnos were likely being 4:18 · influenced by a hidden world one with 4:21 · between five and 10 times the mass of 4:23 · Earth in short a missing ninth planet in 4:27 · the seven years since that Cosmos 4:28 · shaking announc M the theory has been 4:30 · refined today is thought the planet 9 is 4:32 · smaller than originally estimated closer 4:34 · to six times the mass of Earth rather 4:36 · than 10 there are also now 11 TN 4:38 · identified as having been perturbed by 4:40 · its orbit rather than just six still the 4:43 · basic outlines of the theory remain 4:45 · intact the idea that there may be a 4:47 · whole other world Beyond Neptune a 4:49 · neighbor Humanity has remained ignorant 4:51 · of even as we've gained the ability to 4:54 · detect planets in other solar systems if 4:56 · that's the case and another planet is 4:58 · really there then it raises an obvious 5:00 · question what's it like planets in our 5:03 · solar system are divided into three 5:05 · distinct categories you have the rocky 5:07 · terrestrial worlds Earth Venus Mars and 5:09 · Mercury then you have the gas giants 5:11 · like Jupiter and Saturn and finally 5:12 · you've got the ice giants including not 5:14 · just Neptune but also the gassy Glory 5:17 · that is Uranus if you were feeling 5:20 · generous you could also add to that list 5:21 · the dwarf planets but the main point 5:24 · isn't whether our solar system contains 5:25 · three or four classes of Worlds but that 5:28 · whatever the true number finding Planet 5:30 · 9 would increase that total that's 5:33 · because Planet 99's estimated Mass Falls 5:35 · between that of Earth and Neptune 5:37 · meaning one of two outcomes is likely 5:38 · it's either a rocky super Earth or a 5:41 · gaseous sub Neptune either way finding 5:43 · it would be extremely exciting imagine 5:46 · for a second how paleontologists would 5:48 · feel finding a living Mammoth right now 5:51 · we only know these creatures from 5:52 · tracers left over from bygone eras to 5:55 · suddenly go from working with vague 5:56 · outlines to having a living creature to 5:58 · study would be pretty mind expanding in 6:01 · a way that's sort of how planetary 6:03 · scientists would feel discovering a sub 6:05 · Neptune in our backyard obviously the 6:08 · analogy isn't perfect sub Neptunes are 6:09 · extremely common across the Galaxy 6:11 · whereas living mammoths are uncommon to 6:13 · the point of being non-extinct still it 6:16 · hopefully gives you some vague idea of 6:18 · how awesome such a find would be how it 6:20 · would help unlock the secrets of 6:22 · planetary formation in both distant star 6:24 · systems and inside our own and that last 6:26 · point there is key so far from the Sun 6:29 · there's no no way a sub Neptune or super 6:31 · Earth could have been created where it 6:33 · now orbits instead it must have been 6:36 · born closer in only to be flung outwards 6:38 · during an era of chaos caused by 6:40 · Jupiter's early movements some think the 6:42 · reason Uranus is tilted on its side is 6:44 · due to a chance interaction with a 6:46 · migrating planet nine alternatively it 6:48 · might have once belonged to another star 6:50 · only to be captured by our Sun's gravity 6:52 · as the two systems swept by one another 6:54 · long ago of course this is all just 6:57 · speculation a towering edifice of of 6:59 · theory built ATP a bunch of extremely 7:01 · distant objects moving in some weird 7:03 · ways yet that doesn't mean the 7:04 · foundations for this Tower aren't solid 7:07 · after all Humanity has already made 7:09 · major planetary discoveries based on 7:10 · orbital disturbances most famously this 7:13 · includes discovering Neptune ever since 7:15 · William herel first sted hungrily at 7:17 · Uranus people have been aware that 7:19 · planet 7's orbit was kind of off like 7:22 · something big was influencing it in 1846 7:25 · Urban Laria did the calculations and 7:27 · pinpointed exactly where that unseen 7:29 · object was the same evening he alerted a 7:31 · German astronomer and Neptune was 7:34 · discovered it's an episode that shows 7:36 · the value of paying attention to 7:37 · seemingly small irregularities 7:39 · consciously or not today's astronomers 7:42 · are all hoping to repeat laria's trick 7:44 · and discover Planet 9 that is if we 7:47 · haven't discovered it already in the 7:49 · cases of Uranus Neptune Pluto and ays 7:53 · all four bodies turned out to have been 7:55 · cited long before their official 7:57 · discoveries allbe by people who didn't 7:58 · realize what they were looking at 8:00 · Neptune for example was recorded by 8:01 · Galileo in 1612 but mistaken for a star 8:04 · a photographic plate of Aris meanwhile 8:06 · has been found dating to 1955 that means 8:09 · there's a fair chance that if Planet 9 8:10 · exists signs of it are already hiding in 8:13 · some forgotten or overlooked data 8:15 · somewhere we even have a potential 8:16 · candidate back in 1983 astronomer 8:18 · Michael Rowan Robinson undertook a 8:20 · planet Hunting Expedition using the very 8:22 · first infrared Space Telescope at the 8:25 · time he thought he' found nothing but 8:26 · after Brown and bat again published 8:28 · their planet theory he went back and 8:31 · Revisited his work there he found three 8:33 · potential matches for the missing World 8:35 · although the low quality of the 8:36 · detections makes confirming them 8:38 · impossible and that last Point brings us 8:40 · neatly on to our next chapter with seven 8:42 · years of searching under our Collective 8:43 · belts you might be starting to wonder 8:46 · why if we know roughly where it should 8:48 · be we haven't found Planet 9 the answer 8:52 · sadly is that finding a missing Planet 8:53 · at such distances even one close in size 8:56 · to Neptune is near impossible of after 8:59 · refining their work Brown and bat again 9:01 · recently made a welcome announcement 9:03 · rather than an orbital journey of more 9:04 · than 18,000 years they instead expect 9:06 · Planet 9 to circle the sun once every 9:08 · 7,400 years that means it should be 9:10 · closer and brighter than initially 9:12 · anticipated and therefore easier to see 9:14 · in theory the news was great slicing 9:15 · over 10,000 years off an object's orbit 9:17 · sharply reduces the amount of distance 9:19 · it covers in Practical terms though an 9:21 · object that takes over 7,000 years to 9:23 · orbit the Sun is still capable of 9:24 · traveling very very far away from us 9:27 · Pluto's orbit for comparison takes Sun 9:29 · 250 years and while sedna's 11,400 year 9:32 · orbit is longer than Planet 9es sedna 9:35 · always discovered when it was near perah 9:37 · helon the point when an object is 9:39 · closest to the Sun by contrast Planet 9 9:41 · is thought to currently be at its 9:43 · furthest point that means looking for a 9:45 · very very tiny spec moving very very 9:48 · slowly against the Milky Way Starfield 9:50 · so far from the Sun the missing world 9:52 · will be reflecting very little light 9:54 · making it hard to detect invisible 9:55 · wavelengths it temperature is also 9:57 · likely to be very very low perhaps 9:59 · causing it to only radiate the far 10:02 · infrared Spectrum the word far there is 10:05 · the important part because it means it 10:06 · will be invisible to even the James web 10:08 · Space Telescope which is incapable of 10:10 · observing things in the far infrared 10:11 · range indeed observing extremely distant 10:14 · things in infrared can come with its own 10:15 · set of problems a 2022 study by cedrick 10:18 · Chris and sergeants reported in Universe 10:20 · today using two infrared Sky surveys 10:22 · taken 20 years apart initially found 500 10:25 · potential candidates for Planet 9 in the 10:26 · data but when they dug into them 10:28 · individually they found the majority 10:29 · were Galactic cirrus clouds of 10:31 · Interstellar dust that radiate in 10:33 · infrared since Planet 9 is assumed to 10:35 · currently be hidden by the Milky Way 10:37 · Starfield such false positives would 10:39 · plague any surge now these are not 10:42 · insurmountable problems but overcoming 10:44 · them will require not just superhuman 10:45 · patience and lots and lots of telescope 10:47 · time but also knowing exactly where to 10:49 · look when we say something like Planet 9 10:51 · is currently moving against the mway 10:53 · Starfield it can be a little misleading 10:55 · as it makes it sound like we've got a 10:56 · rough location but this location is 10:59 · rough in the same way that dropping a 11:01 · marble out a jet flying over the United 11:03 · States and declaring it landed in the 11:04 · midwest is sure it's technically correct 11:07 · but it won't really help anyone wanting 11:08 · to track down and find that marble as 11:10 · two planetary scientists explained in an 11:12 · article for conversation the problem is 11:14 · that these telescopes usually have a 11:16 · very small field of view it is like 11:18 · using a microscope to scan a very large 11:20 · area for something small that we've 11:22 · dropped this helps explain why so many 11:24 · Searchers since 2016 have come up 11:26 · empty-handed space Australia helpfully 11:28 · listed some of the key instruments and 11:29 · surveys so far used the wise telescope 11:32 · the Gia spacecraft the test telescope 11:34 · the dark energy survey and the Catalina 11:36 · Sky survey as well as looking through 11:38 · old data from stuff like the Siding 11:40 · Spring survey and the zwiki transient 11:42 · facility survey all turned up nothing 11:45 · nor is it really possible to use the 11:47 · orbits of tnos disrupted by Planet 9 to 11:50 · pinpoint its location because we know 11:51 · comparatively little about the Kyer belt 11:54 · it's tough to really zero in on objects 11:56 · that are behaving in weird ways and draw 11:58 · conclusions from on them if we could see 12:00 · and understand the belt's whole 12:02 · structure we would be able to pinpoint 12:03 · areas where a large planet has disrupted 12:06 · things at the moment though we're 12:07 · working with around a dozen objects that 12:10 · may seem to be orbiting weirdly just as 12:12 · a side effect of selection bias if 12:15 · that's the case then Planet 9 may be 12:17 · nothing more than a goost in the data a 12:19 · phantom conjured Bon squinting at a 12:21 · blurry and incomplete picture and hoping 12:23 · desperately to see something luckily 12:25 · combining all surveys and simply 12:26 · pointing telescopes at trunks of the 12:27 · night sky and hoping aren't the only 12:30 · ways to track down a missing Planet it 12:32 · may be that we're soon able to narrow 12:34 · down our hidden neighbors location using 12:36 · some pretty clever methods as Elton John 12:39 · once sang of Mars planet 9 in fact is 12:41 · cold as hell but you know what might not 12:43 · be so cold any moons the planet has of 12:46 · all the planets in our solar system only 12:48 · two Mercury and Venus do not have any 12:50 · moons that means it's highly likely 12:52 · Planet 9 has some companions on its 12:54 · lonely Journey Through the void 12:56 · especially when you consider the region 12:57 · it inhabits is full of teer as the most 12:59 · massive gravity Source around it would 13:01 · be amazing if Planet 9 hadn't captured 13:04 · at least a few TN over the years just 13:06 · look at Neptune there are good reasons 13:08 · to believe its large Moon Triton is a 13:10 · former dwarf planet dragged into the ice 13:12 · giants orbit at this stage you might be 13:15 · wondering why all of this matters surely 13:17 · any moon so far away from the Sun is 13:19 · going to be equally cold and therefore 13:22 · even harder to see than its host World 13:25 · well perhaps not education University of 13:27 · Hong Kong scholar man her Chan recently 13:30 · released a pre-print paper examining the 13:32 · role of tidal heating on any moons 13:34 · Planet 9 may have tidal heating is a 13:36 · super interesting thing even for Layman 13:38 · such as ourselves the result of gravity 13:40 · pulling on an object in a non-uniform 13:42 · way creating friction and thus heating 13:44 · it's thought to be the mechanism that 13:46 · keeps subsurface oceans liquid on moons 13:48 · like Enceladus Europa and Triton in this 13:51 · case though the paper isn't concerned 13:53 · with liquid water but with the heat that 13:56 · would be released from this process that 13:58 · would make Planet 9's moons potentially 14:00 · hotter than the planet itself meaning 14:02 · wouldst stand a better chance of picking 14:03 · them up in infrared surveys of the night 14:05 · sky it's a fascinating concept and just 14:07 · one of a recent slew of bold theories 14:10 · put out on how we could detect the 14:11 · invisible World another involves using 14:13 · an even wider mechanism the path of an 14:15 · Interstellar asteroid cnos 14:19 · 201418 is most famous as the meteor that 14:22 · crashed offshore in Papa New Guinea in 14:24 · 2014 and later became the target of a 14:26 · sea dredging Expedition led by lobe who 14:29 · claims that it might be a piece of alien 14:31 · equipment but whether or not it's the 14:33 · staff of fox mold's wet dreams that may 14:36 · have a far more pric use according to 14:39 · Hector soas Navaro and ignatio Trio 14:42 · Cabrera of The Institute astrophysic de 14:44 · canarius by tracing its path back across 14:46 · the solar system we can see whether it 14:48 · interacted with a large object on its 14:50 · way in 2023 they published a paper doing 14:53 · just that in it they demonstrated how 14:55 · the asteroid likely came from the region 14:56 · of space where Planet 9 is is most 14:59 · likely to be located if the planet is 15:01 · indeed there then the odds of the meteor 15:03 · interacting with its gravity are 15:04 · something like 15:06 · 99.9% that means if we can figure out 15:08 · when cnos S14 entered our solar system 15:11 · we can plot its trajectory backwards and 15:13 · pinpoint where Planet 9 was when the 15:15 · meteor brushed by circus novaro and 15:18 · Cabrera think this places the missing 15:20 · World quote very close to the point 15:22 · where the constellations Aries Taurus 15:24 · and cus meet now to return to our 15:26 · analogy from the last chapter having 15:27 · confirmation of this world would be like 15:29 · narrowing our airplane drop marbles 15:31 · location down from the Midwest to 15:33 · somewhere in downtown De Moine still a 15:36 · huge area to search but one that's now 15:39 · in the Realms of possibility but perhaps 15:41 · the planet 9 location Mission we like 15:43 · the most is the one that would involve 15:45 · probing Uranus the most recent decad or 15:47 · survey selected as highest priority for 15:49 · NASA a dedicated mission to Planet 7 15:51 · when it finally launches assuming the US 15:53 · Congress can settle down long enough to 15:55 · start funding science again the craft 15:57 · will spend between 10 and 15 years 15:59 · simply traveling through the void 16:00 · between Jupiter and its Target rather 16:03 · than an annoying pause though that 16:05 · decade could prove invaluable to science 16:07 · when an interplanetary craft is on a 16:09 · long cruise like that it occasionally 16:11 · checks in with a station on Earth you 16:13 · know just a call to say where it is and 16:15 · how it's doing so we know it's not about 16:17 · to go flying off course or activate any 16:19 · hidden monoliths or anything normally 16:21 · these pings are relatively rare but if 16:24 · we could make the Uranian probe fire off 16:26 · enough we'd be able to see over time how 16:29 · Planet 99's distant gravity affected the 16:31 · craft it would be a subtle effect a near 16:34 · invisible tugging but it would also be 16:36 · enough for us to use that data to narrow 16:38 · down Planet 99's location perhaps enough 16:40 · so that astronomers could even be 16:42 · convinced to start pointing powerful 16:44 · telescopes in that direction knowing 16:46 · that they had a decent probability of 16:47 · finding something of course NASA won't 16:49 · be ready to investigate the Majesty of 16:51 · Uranus for several years that means 16:52 · there's a good chance we'll have located 16:54 · the planet long beforehand the ver 16:56 · Reuben observatory in Chile is current 16:58 · ly the most exciting science project not 17:00 · enough people are talking about an 8.4 M 17:03 · telescope it will photograph the entire 17:05 · visible night sky every couple of days 17:07 · producing mountains of data that 17:08 · researchers will be able to sift through 17:10 · looking for signs of unknown objects if 17:12 · Planet 9 really is out there this is the 17:15 · most likely way will find it what if it 17:16 · isn't what if the VC reubin comes online 17:19 · only to return nothing avoid where the 17:21 · missing sub Neptune should rightly be 17:24 · incredibly that might be even more 17:25 · exciting than actually finding it 17:27 · perhaps the most interesting thing about 17:29 · planet 9 is its inherent sense of 17:30 · mystery the feeling that it could be the 17:32 · world brown and badan theorized back in 17:35 · 2016 or it could be something totally 17:37 · different you know how you sometimes see 17:39 · images of old maps that Drew on 17:40 · hypothetical Australia before it was 17:42 · ever actually cited well that's kind of 17:45 · where we are with Planet 9 we think it's 17:47 · out there we think we know roughly where 17:49 · it is beyond that we might as well just 17:52 · write here be Mysteries so if it turns 17:54 · out the planet N9 isn't a missing 17:55 · superar or a sub Neptune what might it 17:58 · be the sist theory is that it really is 18:00 · a planet just not one on the scale that 18:02 · brown and ban imagined the trouble with 18:05 · a sub Neptune is that it would be by far 18:07 · the most powerful gravitational force in 18:09 · the region so powerful that models 18:11 · predict it would mess up the orbits of 18:13 · far more TN than we're currently 18:14 · witnessing in 2023 this led planetary 18:17 · scientists Patrick safia Leck liaa and 18:20 · takishi ETO to theorize in a paper 18:22 · published in the astronomical journals 18:24 · Planet 9 might be smaller small enough 18:26 · to be comparable with Earth there is 18:28 · research showed that a Planet Air 1.5 18:30 · times the mass of Earth orbiting between 18:32 · 250 and 500 astronomical units from the 18:34 · Sun could account for all the weird tnos 18:37 · that we're aware of especially if its 18:39 · orbit is tilted to 45° that would make 18:41 · Planet 9 not some hidden giant but a 18:43 · real life mest a near Twin of our worlds 18:47 · likely cast outward at some point in the 18:49 · early solar system to the icy Realm of 18:51 · the Kyper bels this though is just the 18:54 · sanest explanation further up the 18:56 · weirdness scale You' get to what we like 18:58 · likely be the most exciting outcome of 19:00 · all that planet 9 is actually a

In the picture above, the arrows show which direction the planets' and Pluto's axes of rotation point. Notice Pluto's and Uranus' point along the same plane as their orbits, instead of more or less "up and down."Credit: NASA/JPL-Caltech |

"To Pluto And Far Beyond" By David H. Levy, Parade, January 15, 2006 -- We don't have a dictionary definition yet that includes all the contingencies. In the wake of the new discovery, however, the International Astronomical Union has set up a group to develop a workable definition of planet. For our part, in consultation with several experienced planetary astronomers, Parade offers this definition: A planet is a body large enough that, when it formed, it condensed under its own gravity to be shaped like a sphere. It orbits a star directly and is not a moon of another planet.
“Planet 9 this invisible world is currently only theoretical but since it was first proposed in 2016 evidence has been stacking up that it may be out there “

Not true. Planet 10 (or planet x) was proposed back in the 1980s. There was an article in OMNI or astronomy magazine (I forget which) that proposed that they had measured some gravitational anomalies that can only be explained by the presence of another planet. They called it planet 10 then because pluto was still considered a planet at that time.
But is this elusive Planet really a planet or is it another Celestial body?
You can see the question like that comes up , because Pluto had been called the ninth planet for so many decades , and then it was downgraded.
So perhaps another celestial object is out there , but is it really a planet?
Yes, but I just hope they don’t name it anything even close to the planet they call Uranus. Maybe instead name it swampbottom or something.

Just give back Pluto...and nobody gets hurt! ;)
egad, that would be terrible
It will be names Aaliyah De’ Ja’ Quintha...
3 biggest lies:
1. Epstein killed himself.
2. Pluto isn’t a planet.
3. The check is in the mail.
I second that suggestion. 😃
What the @$#%#! ya mean, you’re not sending the %@#$FDV check?!?
Ah, I’m glad your priorities are straight!
