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."

Neptune order in the solar system?
Neptune is the eighth planet from the Sun. You may say it is the last planet if you exclude Pluto.
What are 2 important things about Neptune?
Neptune is the eighth and farthest planet from the Sun in our solar system. It is known for its vivid blue color, which is due to the presence of methane in its atmosphere. Neptune has the strongest sustained winds of any planet in our solar system, with speeds reaching up to 1,200 miles per hour.
What is Neptune's location from the sun in or outer planet?
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.
What planet is farthest to the moon?
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.
What new planets have been discovered recently this year?
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.
Which is the last planet of the solar system?
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....
Did the planet Neptune shrink in diameter?
Yes, scientists say Neptune is shrinking as we know it.
Neptune order in the solar system?
Neptune is the eighth planet from the Sun. You may say it is the last planet if you exclude Pluto.
Which is the coldest planets?
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.

The outer most planet is?
Most say Neptune. Pluto isn't a planet, but counting dwarf planets, Eres. A little dwarf planet far beyond the reach of the sun, but still orbiting the sun.
Are there bushes on Neptune?
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.
Does planet Neptune have good craters?
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
