Lazarus comet
A Lazarus comet is a small body within the main asteroid belt that is not an asteroid, but a comet that has been trapped and may be re-energized into being a live comet.[1] Astronomers are referring to this region of the asteroid belt as a comet graveyard, but calling these comets "Lazarus" because of their potential to be "resurrected".[2]
