Astro Quiz 43: Meteoroid?
Question #43 – What is a meteoroid? Is it different from a meteor or a meteorite?
A meteor is a small piece of comet or asteroid that burns up in the Earth's atmosphere. We see it as a streak of light across the night sky. A meteoroid is what this piece of comet or asteroid is called when it is traveling through interplanetary space. If a meteor does not burn up in the Earth's atmosphere and lands on the ground, it becomes a meteorite. Meteorites can be seen at most science museums as well as the Adirondack Sky Center office and classroom.
More information about the difference between meteoroids, meteors and meteorites can be found on this NASA Solar System Exploration page.
