About 4.5 billion years ago, along with all the other planets.
Neptune was made from an exploding nebula far off in space , in which all of the other planets , including the sun , was formed.
Earth and Neptune formed together so it has lived the same number of Earth Years as Earth has.
Neptune came from the big bang like the rest of the planets it was formed by all of the gasses that were let off when the big bang happened.
Neptune was formed around 4.5 billion years ago, along with the other planets in the solar system. Neptune is the fourth largest planet, after Jupiter, Saturn, and Uranus. Almost identical in size to Uranus, its sister planet, Neptune was formed, along with the other planets, from the primordial Solar Nebula. While the larger planets (Jupiter and Saturn) received the lion's share of the nebula's hydrogen and helium, Uranus and Neptune appear to have received only rock and ice
It has been orbiting the sun since it was formed.
its not the farthers planet.. whoever thought it was is stupid :) haha
Yours and mine. It was formed right here, a few billions of years ago
Because Triton revolves around Neptune opposite its rotational direction it is considered retrograde. This indicates that it was likely a planetoid that was captured by Neptune's gravity rather than having formed in orbit around Neptune.
Neptune was formed around 4.6 billion years ago, at the same time as the rest of the solar system.
Despina is one of Neptune's moons, and it was discovered by the Voyager 2 spacecraft when it passed by Neptune in 1989. However, the moon itself is believed to have formed billions of years ago, alongside Neptune and the rest of the solar system.
Water as well as other more complex molecules have been found in space.
Neptune. It's largest moon Triton orbits Neptune a direction opposite to the direction Neptune orbits the Sun. So either Triton orbits Neptune in a clockwise direction whilst Neptune orbits the Sun in a counterclockwise direction.. or vice versa. Hope this is what you meant! :D ~Riley
