29P/Schwassmann–Wachmann is a comet found by the German astronomers Arnold Schwassmann and Arno Wachmann at the Hamburg Observatory in Bergedorf. It is unusual because it moves in a nearly circular orbit between those of Jupiter and Saturn, so it stays cold and far from the Sun and is classed as a Centaur. Despite that, it frequently goes through sudden outbursts in which it brightens many times over, probably because of internal pressure in its icy nucleus, which makes it a favourite target for amateur observers. Its large and mysterious carbon monoxide activity has been studied in detail by space and ground telescopes, and the comet is expected to remain in this orbit for a long time.
