Neptune


The planet Neptune is the 8th planet from the sun. Like the other outer planets, it is also made up of gases. Surprisingly, Neptune has a very hot center, containing twice the heat from the sun. Its well-known for its blue color, which comes from the amount of methane gas in the atmosphere. Neptune has a feature called the great dark spot, another storm similar to Jupiter's red spot.

Named after the Roman god of the sea for its color, Neptune has a diameter of 49,532 km. It has 13 known moons, and 4 rings. Since the rings are small and thin, few people know about them. Pluto's orbit sometimes passes in front of Neptune, making Pluto the 8th planet for a short while.

Compared to most planets, Neptune is extremely cold, only second to Pluto. Its atmosphere is almost all hydrogen and helium, with a smaller amount of methane. Voyager 2 is the only source of information we have about Neptune except for what we can see on Earth. Hopefully one day we can learn more about this distant planet.
