Nice Neptune

Neptune is the furthest planet from the Sun. It is a large, watery planet with a blue-colored atmosphere. Neptune is known for its stormy and violent weather, such as high winds and hurricanes. The hurricanes move across Neptune's surface and create a "Great Dark Spot" on the surface of the planet. Neptune has six rings and 13 known moons.
