If the object is larger than a meteoroid, it is called an asteroid; smaller than that, it is interplanetary dust. The current official definition of a meteoroid from the International Astronomical Union is “a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom.” A meteor typically occurs in the mesosphere, and most visible meteors range in altitude from 75km to 100km. A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and impact with the ground without being destroyed. An Asteroid; Asteroids, sometimes called minor planets or planetoids, are bodies—primarily of the inner Solar System—that are smaller than planets but larger than meteoroids, but exclude comets A Comet; A comet is a small Solar System body that orbits the Sun and, when close enough to the Sun, exhibit
