Distinguishing between meteoroids, meteors, meteorites and comets can be a challenge even for those interested in astronomy. The differences are rather elementary, however, once one understands the definitions. The following guide can help you understand these astronomical terms. Meteoroids, meteors, meteorites are terms that are...
