Pluto was discovered on the 18 February 1930, and is the second closest dwarf planet to the Sun. Before being a dwarf planet it was classified as the ninth planet. Pluto is the second most massive dwarf planet with Eris being the biggest.
Pluto's Profile
- Pluto is a very small planet and only has a diameter of 2302 km. Even with its small size it has 5 moons around it. They are Charon, Styx, Nix, Kerberos and Hydra.
- It takes Pluto 246.04 Earth years to orbit around the sun.
- Pluto has a surface temperature of -229 degrees Celsius.
Pluto's size
With a diameter of only 2302 km it is very small compared to the Earth. It's only 1/6 of the size of Earth. Pluto is actually smaller than our own moon.

Pluto's place in the solar system
Pluto is placed between Neptune and the Kuiper Belt.
Pluto is a interesting dwarf planet with some good facts. Its crazy to know how much water there can be on dwarf planets. Pluto may become even more interesting when the spacecraft New Horizon will get close to the planet.

Facts about Pluto
Pluto was discovered on 18 February 1930 by Lowell Observatory
Lowell was looking for the ninth planet.
For the 76 years between Pluto being discovered and the time it was reclassified as a dwarf planet it has completed under a third of its orbit around the Sun.
No spacecraft has visited Pluto - yet
Pluto was reclassified from a planet to a dwarf planet in 2006. This was caused because the IAU formalised the definition of a planet needed to be:
- In a orbit around the Sun.
- Have a sufficient mass for its self-gravity.
- Have a nearly round shape.
- Have cleared the neighbourhood around its orbit.
Through the month of July in 2015 the spacecraft New Horizon, launched in 2006, should fly by Pluto on its way to the Kuiper Belt.
Pluto is one third of water
The water on Pluto is ice, and therefore compact. Which means that there is more than 3 time as much water on Pluto, than all the water in the oceans on Earth. The remaining two thirds are rock.
A spooky dwarf
Pluto is named after the Roman god of the underworld, and the moons after other characters associated with the underworld of Greek and Roman mythology.
