Meteors. Another name commonly used for a meteor is a shooting star. A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. âMeteorâ refers to the flash of light caused by the debris, not the debris itself. If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite.
