Meteorites

A meteorite is an object which has fallen to Earth from space.

Meteors are the flashes of light ('falling stars') produced when meteorites pass through Earth's atmosphere. Other, smaller, pieces of extraterrestrial debris also cause meteors, including grains of dust from comets. While some meteorites are found immediately after their fall, many, called 'finds', have lain on the Earth for many tens of thousands of years prior to their discovery.
