A meteor is an event, not just an object. It happens when small pebble (a meteoroid) enters our atmosphere and burns up. Any pieces that reach the ground are called meteorites. Meteoroids are distinguished from asteroids by being too small to cause much damage at ground level, if they were to hit the Earth.
Topics for this category include meteors, bolides, fireballs, and airbursts.
As a meteor burns up in the atmosphere, it leaves a trail which reflects radio waves for a moment. Radio meteor observers listen for signals briefly reflected off of meteor trails.
