Neptune is one
of the four giant planets (Jupiter, Saturn, Neptune, and Uranus.) Since
it is sometimes the farthest planet from the sun it is a really, really
cold planet. Neptune is only a tiny bit smaller than Uranus.
It doesn't take as long as Earth to rotate once, but its years equal 164.8
There are three satellites that are known to us to Neptune. Neptune has Methane gas in its atmosphere.
Neptune is 17 times the size of Earth.
