The Earth is the third planet from the sun. It is the only known planet that is able to support life. Earth is surrounded by an atmosphere, which enables life to survive on the planet. There are many sections of atmoshpere. The atmoshpere can be divided into these different layers (from lowest to highest part): Troposphere, Stratosphere (the ozone layer is part of the stratosphere), Mesosphere, Ionosphere, and the Exosphere. Moving on... Earth's average distance from the sun is 93 million miles. The polar diameter of Earth is 7,900 miles and the equatorial diameter is 7,926 miles. The length of one year on Earth is 365.26 days. The length of one day is 23.93 hours. Earth weighs 5,970,000,000,000,000,000,000,000,000,000 tons. The density of Earth is 5.52 g/cm cubed.
