It's a long story, and to answer it, we have to go all the way back to when Uranus, the planet before Neptune, was discovered.
Uranus was discovered in 1781, and astronomers started calculating the orbit it should be following around the Sun. However, within a few years, astronomers started noticing the planet wasn't quite following the orbit they'd assigned it; it was slightly out of place. No matter how hard they tried, the mathematicians couldn't manage to calculate an orbit for Uranus that fit the facts.
In 1845, two astronomers, John Couch Adams in England and Urbain LeVerrier in France, working independently of each other, came to the conclusion that there must be another planet beyond Uranus, pulling on it with its gravity and affecting its orbit. They used the discrepancies in Uranus' orbit to calculate where the new planet should be, but couldn't get anyone interested for a long time. It wasn't until 1846 that a German astronomer, Johann Gottfried Galle, using LeVerrier's calculations, decided to look at the spot in the sky LeVerrier had predicted the planet should be - and lo and behold, there was Neptune! So Neptune was discovered by Adams and LeVerrier, writing down their calculations with a pen, before astronomers had ever actually seen it. That's why Neptune was "discovered by pen."
some people say neptune has 8 moons but other say neptune has 11...... neptune is the eihgt planet from the sun.
Neptune is the eighth planet from the Sun. You may say it is the last planet if you exclude Pluto.
It's an outer planet, as it is the eighth planet away from the sun. You could say it is the last planet if you exclude Pluto.
First of all why do you say YOUR solar system?? The planet is neptune and it has 13 moons which are: Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, and Neso.
Scientists have evidence of and say that a new Neptune sized planet lurks beyond the edge of our solar system. There has been no visual sighting of this planet. However it is probably so far out it will be very difficult to find given present technologies.
Since Pluto is now a dwarf planet, the last planet is now Neptune. The most recent planetary discovery occurred in 1930; the newly discovered body was named "Pluto". Since then, it has completed about 1/3rd of a revolution in its orbit around the sun. Nobody can say with certainty that Pluto is the 'last' planet, only that it is the one most recently discovered, the one at the largest known average distance from the sun, and the one with the longest known orbital period. So far....

Yes, scientists say Neptune is shrinking as we know it.
Neptune or Uranus is the coldest Planet. Some reference sources say it's Neptune others say it's Uranus. There's very little difference between them. Neptune is the furthest from the Sun, but it has an internal heat source.

Seeing that we have say that no life lives on any other planet and the plant is a living organism i have to say NO
It doesn't say in the movie, but someone suggested Uranus or Neptune.

what exactly do you mean by good crater?? Neptune would not have any craters on the outer surface because it is a gas planet, the core maybe might have craters but i could not say for sure

With Pluto now regarded as a dwarf planet, the answer is Neptune. There are times when Pluto's orbit takes it inside Neptune for about 20 years at a time out of its 248 year orbit, as it did from 1979 to 1999. So even when Pluto was considered a planet, it wasn't always the furthest away from the Sun.
