Answer 1

Assuming someone has asked YOU this, suspect they are trying to trip you up in regard to the NEW planet:

It even has its own MOON! :D

And no, that's not yet in the encyclopedia. ;)

Answer 2

The discovery of a large Kuiper Belt object beyond Pluto has cast doubts on the status of Pluto as a planet. The problem is that Pluto is totally different in composition, size, orbital elements, to the other outer planets, and is exactly like the so-called Kuiper belt objects - asteroidal objects that orbit beyond Neptune.

The problem is going to be that if you retain Pluto as a planet, you face the prospect in the near future of calling thousands of other objects planets. Some will be as small and smaller than the asteroids in the asteroid belt between Mars and Jupiter. So, then you would have to start calling those planets - and it will never end.

Many astronomers now are discounting Pluto as a planet, and therefore, there are only 8 planets in our system.

As for last planet in the Milky Way, astronomers only know of some planets that orbit stars in our local region. The other side of the Milky Way is about 80,000 light years away. It will be a long while before they can answer your question.

Answer 3

I would say that real planet would be Neptune, since there is a very convincing theory that says that Pluto is just one object from the OORT cloud that happened to pass too close to the Sun to be captured in its gravitational field. Just look at the excentricity of the orbit and the fact that the size does not correlate to the rest of the gas giants. There is something really strange don't you think. So if Pluto is just a "planetoid" along with its satellite Charon, I would say that Neptune is the largest planet.

Answer 4

Pluto but Pluto and Neptune swap places every 5 years.

Answer 5

There's no telling, but the last one in the solar system is generally given as Pluto, although Pluto and Neptune swap which is last every so often.

Answer 6

It's said to be pluto, I was reading an article that said there is a small meteor that is just outside pluto that orbits around the sun.

Answer 7

Xena is being considered by scientist as whether or not it's a planet. It is the last in our solar system. It's impossible to say one plaint is the last is out Galaxy.

Answer 8

I think that there was a planet discovered recently just beyond Pluto. Not sure what it was named.

Answer 9

Better get yourself a set of World Book Encyclopedia's.
You will find some great answers to your questions.

Answer 10

Your mean is in The which solar system?
if you mean in our solar system we found 10th planet and it is the last it name x it has not name right now.
