Neptune is a ball of gas with a metal core.
Neptune, also a huge ball of gas, is usually the 8th planet from the
Sun. However, for a few years (until February 1999) Pluto was actually closer to
the Sun than Neptune. The planet is surrounded by hazy blue clouds and
dark rings. Neptune has a large storm cloud called the Great Dark Spot
and a smaller white cloud called "Scooter" that races around the planet.
