Neptune’s Discovery Neptune was discovered by John Couch Adams in 1846. Neptune got its name from the god of water. A spacecraft called Voyager 2 studied Neptune in 1989.
Interesting Facts Winds howl across the planet at speeds up to 1,490 miles. Neptune is so far away from the sun that it takes 165 Earth years to make one orbit. Very strong winds push clouds across Neptune.
Living on Neptune People could not survive on Neptune because it does not have oxygen.
Water and Gases There is water on Neptune. Neptune’s core has molten rock, water, liquid ammonia, and methane. Hydrogen, helium, and a small amount of methane gives the clouds blue color.
Neptune and Earth Neptune is 2,700,000,000 miles from Earth. Neptune doesn’t have landforms because it doesn’t have a flat surface. A day on Earth is 24 hours; a day on Neptune is 16 hours and 6 minutes. A year on Neptune is 164.79 Earth years.
Summary Neptune has 6 rings and 13 moons. Neptune is so cold because it’s so far away from the Sun. Neptune has water but people can’t live on it because it doesn’t have oxygen.
