Neptune is the eighth and farthest major planet from the Sun. Sunlight is weak out there, yet Neptune is a stormy, active world. Its deep blue color comes from methane in the atmosphere, which absorbs red light. Neptune is an ice giant like Uranus, with hydrogen and helium on top and icy materials deeper down. It was the only planet found by math before it was seen through a telescope in 1846.
🌑 DISTANT
Neptune orbits about 30 times farther from the Sun than Earth does.
