CAPE CANAVERAL, Fla. NASAs New Horizons spacecraft aimed to get up-close and personal with Pluto on Tuesday, on track to zoom within 7,800 miles of the small icy world left unexplored until now.
Its the final destination on NASAs planetary tour of the solar system, which began more than a half-century ago. Pluto was still a full-fledged planet when New Horizons rocketed away in 2006, only to become demoted to dwarf status later that year.
The 3 billion-mile journey from Cape Canaveral, Florida, culminates Tuesday at 7:49 a.m. EDT. Thats when the spacecraft is due to fly past Pluto at 31,000 mph.
The New Horizons team gathered at Johns Hopkins Universitys Applied Physics Laboratory in Laurel, Maryland, wont know for many hours if everything went well. The spacecraft will be too busy taking photographs and collecting information to phone home. A confirmation signal is expected at around 9 p.m. EDT.
New Horizons already has beamed back the best-ever images of Pluto and big moon Charon. Pluto also has four little moons.

traderrob6’s assessment is valid.
https://en.wikipedia.org/wiki/Planet#2006_definition
The prevailing criteria for a planet was changed by a ‘quorum’ of 232 out of 10,000 on the justification that dozens of planets would exist if the definition wasn’t changed.
IMO they’re going with a definition which identifies 8 planets because they can be counted using one’s fingers. Should we now worry about Jupiter being renamed Chikn?
“Ill start watching now. Let me know when the time is up.....................”
Your orbital observations are imperative in determining whether or not pluto is a planet. If it stops and reverses direction like Mars let us know immediately so the Pluto Committee can draw up another Planetary Orbital Exception to Policy letter as there is a long approval process for that.
How many bro’s and ho’s were on the spacecraft team?
It looks like its got some polar ice there. I wonder what unique compound would exist as both a gas and as a solid at those temperatures?
For me, its pretty simple. It is in orbit around a star. It has enough mass to have spun itself into a sphere.
And it has its own moons, icing on the cake. Its a planet.
So does that mean there are others? Who said “9” was the magic number? There might be more. Maybe we’ll get the chance to see some now that we’ve sailed on past Pluto.
If Pluto werent in orbit around the sun, we wouldnt have been able to send a spacecraft there with such precision.

My understanding is that there have been course corrections quite a few times during the 9 year trip to pluto.
I did not make the rules about having to prove an orbit prior to being called a planet, you know.
It is what it is.

...
The operative word being few, and to be more accurate, very small corrections. If Pluto weren’t in orbit around the sun, there wouldn’t be enough fuel for the corrections.
“Whos the goofball?”
Anyone who believes the orbit must be observable in a human lifetime.
The orbit is scientifically provable.
That’s enough.

You just made that part up. No one said in a single person’s lifetime except you.
4-1/2 hours to send it a command
4-1/2 hours for the probe to send an acknowledgement.
It is 3 billion miles away
In comparison, it takes sunlight about 8 minutes to reach Earth.
God’s universe is immense. I am in awe
I agree. The "definition" is not precise enough. Personally, I believe Pluto is a planet. Don't really care what other folk think about it. I think the decision to call it a 'dwarf planet' was a bad one. Shoulda left well enough alone. Call Ceres a dwarf if you want.
For one thing, it shows 9 planets.
WRONG!
For another thing it shows WHITE PEOPLE.
WRONG!
Lastly, it shows that there are only 2 sexes, not the 53 gender identifications we all will be forced to accept.
WRONG!
Beatiful shot. Once again, nice job, Creator of the Universe!
Very, very cool!
From your post:
“We will not have been able to observe that for another 163 years.”
It does NOT need to be “observed”!
It is scientifically PREDICTABLE!!!
Get it?
Course corrections are made because of variations and uncertainties associated with spacecraft performance.
It does NOT need to be observed!
It is scientifically PREDICTABLE!!!
Get it?

Holy moly, friend. Next cup should be decaf.
I have simply stated what scientists use as the criteria for a planet. That’s it.
Is there some reason this disturbs you so?
Pluto was demoted because in 2007 the International Astronomical Union (IAU) had a little problem. Astronomers kept discovering more and more large objects floating in the Kuiper belt, the region of space beyond the planet Neptune. They have so far found over 1000 of these Kuiper Belt Objects (KBOs), including some rather large ones, such as Sedna, Quaoar, Orcus, Haumea, Makemake, and Eris. That last one, Eris, is actually larger than Pluto itself. So the number of planets in the solar system threatened to grow ever larger: 10 planets, 12, 13? Where do you stop?
No “scientist” believes it needs to be “observed”.
