Facts
Neptune is the smallest gas giant in our solar system. It has winds blowing up to 700 mph, and it has storms raging all over the planet. Speaking of storms, the largest storm on Neptune is the Great Dark Spot. The blue color from Neptune comes from the high levels of methane in it's atmosphere. Neptune also has the smallest rings in the solar system, and its rings are almost invisible. Neptune's gravity is also incredible. Scientists predict that one day Neptune's moon Triton will be crushed by Neptune's gravity. The only probe that has visited Neptune is Voyager 2. A year on Neptune is 165 years, and a day is 16 hours.
