I Meteorites Meteorites are fractions of asteroids, the Moon, of planets, or even of comets that land on Earth. Their fall to earth may be accompanied by light and a booming sound. There is an example of a meteorite impact with the Earth in Arizona. Some call the crater, Barringer. An iron meteorite impacted the earth some 50,000 years in the past.
Many people think of meteorites as being one small or gigantic to earth.
There are generally three types of craters defined by meteorite impacts. It is generally made by a small meteorite sizing only up to a few meters. This crater is symmetrical and shaped like a bowl. This type of crater is made by meteorites tens of meters or even several kilometers in diameter. They often are accompanied by ridges and valleys.
