One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet.

Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
