As a result, the nomenclature of the celestial bodies often changes, as scientists develop better ideas of what things are and how they function. The differences ... Webb1. Are asteroids and meteoroids made of similar things?Meteoroids are bits of solid material of different sizes orbiting the Sun. Some bits come from comets, some bits come from asteroids, and a very few bits from the Moon and other planets. All those bits originally came from the same “pot”—the solar nebula—and so they are mostly made of …
