Neptune means:
Neptune was originally only the god of water, but was latter extended to the ocean when he became associated with the Greek god Poseidon (KidsAstronomy.com).
Neptune is very much like Uranus, except for the fact that it is smaller. It also has a giant storm similar to the one on Jupiter, the storm is referred to as the The Great Dark Spot.
It is the methane gas that gives Neptune its blue color because the gas absorbs red light and then the blue reflects back into space. Like the other outer planets Neptune has rings and moons. The rings on Neptune are more faint then on other planets but they still exist.
