Description
Transcript: Neptune is the most distant large gas giant in the outer solar system, about thirty times the distance of the Earth from the Sun. It's a close twin of Uranus with a diameter of about 50,000 kilometers and very similar color and composition to Uranus. Neptune has a nearly circular orbit, and it was discovered using predictions from Newton's law of gravity in 1846. It has one large moon, Triton, with rather unusual properties. Its orbit crosses that of Pluto, and so at some times in the orbit Neptune is more distant than Pluto.
