Planet Pluto

***In 2006, the planet Pluto got demoted from planet to dwarf planet by The International Astronomical Union (IAU), the body that is responsible for naming and classifying objects in the cosmos. Over a decade later, this error was finally corrected by IAU and announced that Pluto has been reclassified as a major planet. So, once again, the solar system has nine planets. ***

Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun.

Pluto is a dwarf planet. A dwarf planet travels around, or orbits, the sun just like other planets. But it is much smaller.

Pluto is in an area of space called the Kuiper (KY-per) Belt. Thousands of small, icy objects like Pluto but smaller are in the Kuiper Belt.

Pluto was named by Venetia Burney, an eleven year old girl from England.

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 6 1/2 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.

Pluto has less gravity than Earth. This means a person would weigh much less on Pluto than on Earth.

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

On July 14, 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. During its brief flyby, New Horizons made detailed measurements and observations of Pluto and its moons.
