What is a meteroright?

Answer 1

METEOROID*.

It's just like a meteor. It shoots down to a planet with high enough gravitational pull, then it crash lands on said planet.

Answer 2

There is no term "meteroright" in the field of meteorology or astronomy. It may be a misspelling of "meteorite," which is a solid piece of debris from a comet, asteroid, or meteoroid that survives its passage through Earth's atmosphere and lands on the surface.
