Neptune Is Neat (and a bit Mysterious!)
Neptune is a neat planet. It is also a bit mysterious. Neptune is four times bigger across than Earth. It is also thirty times further away from the sun. This means that no one can see Neptune without a telescope. It is just too far away. When scientists and satellites have studied Neptune, they have learned some neat and mysterious things.
Neptune is covered with bright blue clouds. These clouds are made of frozen methane. They swirl around the planet at up to 1,300 miles per hour. That is a lot faster than any wind gust here on Earth. In 1989 Voyager 2 found a Great Dark Spot on Neptune. This looked a lot like Jupiter's Great Red Spot. They think that it was caused by a swirling hurricane. But in 1994, it was gone! The Hubble Space Telescope could not find it. It seems to have vanished. How mysterious!
