The earth and the solar system

The earth is a planet that moves around the sun. There are nine planets that move around the sun. The sun and these nine planets together from the solar system. These planets are mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. They are arranged in this order from the sun. The closer the planets are to the sun, the hotter they will be. The further the planets are from the sun, the colder they will be. Thus mercury is the hottest and Pluto is the coldest of all the planets. Earth is neither too cold nor too hot. Thus, life can exist here.
