Dwarf Planets

By Graham Wharton

Introduction

14 billion years ago there was a "bang" and pieces of matter went flying throughout the solar system. The rock planets took some, the gas giants took a ton, and the rest went far out away from the sun. Those extra pieces weren't even known to exist until the 1900's, but they called them part of the "Kuiper belt."

Introduction continued-

The three main and biggest kupiter objects are Eris, Pluto and Ceres. Pluto is the first found and most well known. It was discovered by Clyde Tombaugh.

Pluto facts:

1- If the sun was as tall as a door, Pluto would be the head of a pin.


2- Most of our dwarf planets are 3.7 billion miles from our sun.


3- The dwarf planet Ceres takes 9 hours (Earth hours) to rotate but 4.6 years (also Earth time) to orbit the sun.

4- Dwarf planets aren't rock or gas, but they are made of ice.


5- Most Dwarf planets have moons, but some don't have any.


6- From what we know no Dwarf planets have rings.

7- Pluto and Eris have atmospheres but they're very small.


8- The fist space mission to the kupiter belt is called "Dawn".


9- Because of their climates dwarf planets are unable to support life.

10- Pluto was a planet until 2006 because the other "planets" could clear their orbit, but Pluto can't because it's so small.
