Neptune
Neptune, which is usually the eighth planet from the Sun, is a very cold place. Occasionally, the ninth planet Pluto crosses Neptune's orbit and becomes the "eigth planet". Its bluish color comes from its atmosphere of methane gas. The planet has eight moons and a very narrow, faint ring system. Neptune's atmosphere shows a striped pattern of clouds. This cloud pattern is very similar to that of Jupiter and Saturn. Neptune even has a Great Dark Spot similar to Jupiter's Great Red Spot.
