are relatively small, icy bodies that display extended features when they approach the Sun. The energy from the Sun vaporizes volatiles on a comet's surface, producing a visible coma around the cometary body. Sometimes a comet can produce a long tail radiating away from the Sun.

Comets are (traditionally) celestial bodies that show comas and/or tails. A more modern definition is any planetoid composed primarily of ices, which would boil off if the body was close enough to the Sun. Comets near or beyond Jupiter's orbit are generally stable, as water ice is unaffected by the Sun's warmth beyond about 5 au. Note that pure, .....
