A meteorite is a small extraterrestrial body that impacts the Earth's surface.

While in space they are called meteoroids, and while falling through Earth's atmosphere they are called meteors.

These are small asteroids, approximately boulder-sized or less.

When it enters the atmosphere, air drag and friction cause the body to heat up and emit light, thus forming a fireball or shooting star.
