Earth

Overview
Earth is the third planet from Sol. It is one of the four terrestrial worlds and the homeworld of the human race. It is also the capital of the CEA. It has been the center of human history for obvious reasons. It is possibly one of the most populated human worlds. Earth is about 4.5 billion years old. Life is said to have appeared in the first billion years. Now Earth is approximately 70% Water. The rest of the surface is made up of seven continents and many islands.

Earth has a varied climate, even in current times. Some parts are temperate, arctic, arid, and so on. Many biomes exist such as taiga, tundra, forest, rainforest, jungle, desert, etc. Earth's moon is one reason for all these stable climates. The moon affects tides and stabilizes Earth's tilt.
