In fact, whilst all three have similar origins, they are very different objects. They are remnants of the material left over from that period of time which saw the formation of the solar system.
Comets appear in our skies from time to time.
They vary considerably in their brightness or magnitude . In fact, at any one time there are almost certainly several comets visible to astronomers with large telescopes, but more rarely are there comets visible to the naked eye. In all cases, the comet moves very slowly , and several hours must pass before any significant movement can be noticed against the background of stars. If, on the other hand, you look up into the night sky and see a brief streak of light, then you have witnessed a meteor . Once more these objects vary in brightness, from those far too faint to be seen with the naked eye, to the bright fireballs which occur very occasionally, and can be so bright that they cast shadows.
