| 释义 | meteorite (once / 7457 pages) n A meteorite is a rock that falls to earth after a brilliant meteor has passed through the earth's atmosphere. If you've ever seen a shooting star at night, you can call what you're watching zip brightly across the sky a meteor. If that same meteor makes it through the atmosphere of the earth, its fire burns out and it becomes a meteorite, or a random piece of space debris that may have originally come from an asteroid or comet. The Greek root for both meteor and meteorite is ta meteora, "things in heaven above."
