The impending demise of Kepler-1658b as it orbits its aging star offers an opportunity for scientists to gain insight into the fate of other planets and their evolving solar systems.
...provides a new understanding of the gradual process of planetary orbital decay by offering the first glimpse of a solar system in its final stages.. the ultimate destiny for many planets, including Earth in about 5 billion years... the exoplanet Kepler-1568b has less than 3 million years left before it meets its demise...
The first author is Shreyas Vissapragada, a 51 Pegasi b Fellow at Harvard University and the Smithsonian Institution...
The ill-fated exoplanet is designated Kepler-1658b. As its name indicates, astronomers discovered it with the Kepler space telescope, a pioneering planet-hunting mission that launched in 2009. This world was the very first new exoplanet candidate Kepler ever observed, at which point it was dubbed KOI 4.01 — the 4th Object of Interest identified by Kepler. (KOIs 1, 2, and 3 had been identified before Kepler’s launch.)...
Kepler-1658b is a so-called hot Jupiter, the nickname given to exoplanets on par with Jupiter’s mass and size but in scorchingly ultra-close orbits about their host stars. For Kepler-1658b, that distance is merely an eighth of the space between our sun and its tightest orbiting planet, Mercury. And unlike Mercury’s 88-day orbit, Kepler-1658b whips around its star in just 3.8 days.
For hot Jupiters and other planets very close to their stars, orbital decay and collision look inevitable. But measuring how exoplanets circle down the drains of their host stars has proven challenging because the process is excruciatingly gradual. In the case of Kepler-1658b, the new study reports that its orbital period is decreasing at about 131 milliseconds (thousandths of a second) per year.

Thanks Red Badger, nice twofer.

I just bought there. It’s really cheap.
Well, SOMETHING is going to kill ya, eventually. ;)
I just want ‘scientists’ to give us back Pluto. And a Flying Car. Been waiting on that since 1960. ;)
Right? When I was a kid, I fully expected there to be flying cars when I got old enough to drive.
But there are only flying buses. 😖
Kepler-1658b was doomed, not because of its proximity to its mother star, but because of climate change that the beings on that planet failed to pay attention to.
“The impending demise of Kepler-1658b”
OMG! NOT Kepler-1658b!
In 3,000,000 years it is going to crash into its sun.
Nancy Pelosi will still be around to witness it.
Hard to believe but true. I still can't believe it myself. I mean, yesterday things were just fine, and now today it's headed to destruction. It just proves there are no guarantees in life.
No guarantee of space either. It’s disgusting to see how much we’ve been lied to about.
Biden must send money to the population of that planet. There is untapped adulation and love for him there, as well as a source of future votes. Never let a crisis go to waste.
Most likely has already happened. It’s like us getting the local news delayed 100,000 years.
This is why I see most astronomical efforts - beyond our solar system - as perhaps interesting but otherwise a huge waste of time and money. Those ‘fantastic,’ human-colored images of the cosmos taken by Hubble and now by James Webb after thousands or millions of years of delay, are, in any practical sense, no more than pretty pictures for my wall.
One exception could be finding that Earth-killing asteroid soon enough to call Bruce Willis to save us.
This is not to disparage your efforts, sir, in presenting such information to interested parties.
My mistake! Keplar still has 3 million years left :)
Well, there are trucks now with hands-free driving, so guess that’s SOMETHING? ;)
But for the life of me, I cannot figure out what POSSIBLE application that has in The Real World, other than to clap along to ‘We Will Rock You’ as they show on the commercials!
*ROLLEYES*
...One exception could be finding that Earth-killing asteroid soon enough...
The point is, pure research has to be done all the time in order to even become aware of such things. If we already knew everything -- and we never will -- there'd be nothing else to know, and in examples like that one, nothing to worry about. The threat of big impacts was whistled past many a graveyard until the 1994 SL-9 impacts on Jupiter, and that was not even 30 years ago. Doubting the possibility now seems absurd -- the fact is, it was absurd before.
They simply need to look out the window.
Whew! Then there is still time to raise taxes to save that planet....
Those are not flying busses, They’re cattle cars. ;-)
I am sorry, I should have not thrown the Bruce Willis comment. The point is, looking at images from half-way across the universe, and at great expense, have no practical value, gussied-up ‘research’ included, beyond the guesstimated colors on pretty pictures.
We did Hubble, fine. The James Webb is not needed for any useful reason.
I’d prefer to spend those $billions on activities within the greater solar system, to include the Ort cloud and such as that, where all that cash could be put to effective use.
Research isn't about pretty pictures. Your Bruce Willis comment just showed the irony.
