Chondrite Meteorites . Meteoroids become meteors when they crash into Earths atmosphere and the gases surrounding them briefly light up as shooting stars. While most meteors burn up and disintegrate in the atmosphere, many of these space rocks reach Earths surface in the form of meteorites. By studying meteorites we can learn about early conditions and processes in the solar systems history. They come from the cores of asteroids and account for about 5 percent of meteorites on Earth.

Most iron meteorites are thought to be the cores of asteroids that melted early in their history. It is used to describe the streak of light produced as matter in the solar system falls into Earth's atmosphere creating temporary incandescence resulting from atmospheric friction.
