Welcome to Neptune
Neptune is the eighth and farthest planet from the Sun in our solar system. It is a mighty gas giant known for its stunning deep blue color.
Discovered in 1846, Neptune is named after the Roman god of the sea. With fierce winds and storms, it occasionally glimpses the Great Dark Spot, a storm as vast as our Earth.
Curious to explore more? Neptune takes about 165 Earth years to complete one orbit around the Sun. Its atmosphere consists mainly of hydrogen, helium, and trace amounts of hydrocarbons and possibly nitrogen.
