Neptune

Neptune is the last official planet in our solar system. It is blue just like Uranus. When Neptune was first discovered, they did not see it, they mathematically figured it out. When scientists distinguished that something was interfering with Uranus’s orbit pattern, they had called the interferer Neptune, then saw it with a telescope. Its core is made of rock and is about as big as the Earth. It has, not rings but arcs because they are incomplete arcs around Neptune. Its day is 16 hours, but a year is 165 earth years. Its atmosphere is made of Hydrogen and Helium. Its winds can blow up to 1240 miles an hour there. It has 13 moons orbiting it. Neptune is named after the sea god because of its sea blue color.
