A comet is an icy body that releases gas and dust as it approaches the Sun, forming a glowing coma and tail. Periodic comets like 10P/Tempel 2 return on predictable schedules. Comet brightness is notoriously difficult to predict — some become naked-eye objects while others require binoculars or telescopes.
