Pluto

Pluto is a dwarf planet. Clyde Tombaugh discovered Pluto in 1930. He was an astronomer from the United States.

Venetia Burney named Pluto that same year. She was an 11-year-old girl from England.

Pluto is in the Kuiper Belt, a group of asteroids further away then Neptune to the sun.This distant realm is populated with thousands of miniature icy worlds, which formed early in the history of our solar system. These icy, rocky bodies are called Kuiper Belt objects.

Pluto is not very big. It is only half as wide as the United States. Pluto is only 2,300 kilometers wide. Pluto takes 248 Earth years to go around the sun. If you lived on Pluto, you would have to wait 248 Earth years to celebrate your first birthday. One day on Pluto is about six and a half days on Earth.

Pluto is very, very cold. It is much colder than Antarctica. It is so cold that Earth’s air would freeze into a kind of snow there. We would dye of freezing to death really quickly.

Pluto has less gravity than Earth. This means a person would weigh much less on Pluto than on Earth. Pluto’s gravity is about six percent of Earth’s gravity, which would mean you would way 6% of your current weight.

Pluto has five moons. Its largest moon is named Charon. Charon is about half the size of Pluto. Pluto’s four other moons are named Kerberos, Styx, Nix and Hydra.

From 1979 to 1999, Pluto was actually closer to the sun than Neptune, and in 1989, Pluto came to within 29.8 AU of the sun, providing rare opportunities to study this small, cold, distant world.
