The '''Earth''' is a planet in the [[Solar System]], orbiting [[Sol]]. Earth is the only known planet capable of supporting life, containing water, reasonable levels of oxygen, and a stable temperature range. Geometrically speaking, Earth is the largest of the terrestrial (rocky) planets in the solar system.

Estimates by geologists of the age of the Earth give about 4.55 billion years. This estimate is primarily based on radioactive dating of meteorites. The extreme majority of scientists conclude that the Earth formed by natural processes, specifically by the accumulation of debris orbiting the sun billions of years in the past. Indeed, astronomers have detected dust lanes around other stars that indicate planet formation is a common and ongoing process.
