Is Neptune colder than Earth?

Neptune is the eighth and farthest planet from the sun but it is not the coldest. Our solar system 's blue gas giant is far larger than Earth, at more than 17 times Earth's mass and nearly 58 times Earth's volume, according to NASA. Neptune's rocky core is surrounded by a slushy fluid mix of water, ammonia and methane ice.

Is Neptune a gas giant?

Neptune, like Uranus, is an ice giant. It’s similar to a gas giant. It is made of a thick soup of water, ammonia, and methane flowing over a solid core about the size of Earth. Neptune has a thick, windy atmosphere. One day on Neptune goes by in 16 hours. Neptune has such a long journey around the Sun it takes 165 Earth years to go around once.

How did Neptune get its name?

The planet is named after the Roman god of the sea. This picture of Neptune was produced from images taken by NASA’s Voyager 2 in the summer of 1989 as it became the first spacecraft to fly by the planet. Eyes on the Solar System lets you explore planets, moons, asteroids, comets, and the spacecraft exploring them from 1950 to 2050.

Why is Neptune called a planet?

It is designated by the symbol ♆. Neptune is named for the Roman god of the sea, who is identified with the Greek deity Poseidon, a son of the Titan Cronus (the Roman god Saturn) and a brother of Zeus (the Roman god Jupiter). It is the second planet to have been found by means of a telescope.

How did Neptune form?

Neptune took shape when the rest of the solar system formed about 4.5 billion years ago when gravity pulled swirling gas and dust in to become this ice giant. Like its neighbor Uranus, Neptune likely formed closer to the Sun and moved to the outer solar system about 4 billion years ago.
