Quick Answer

Halley's Comet orbits the Sun about every 75 to 76 years; it last passed closest to the Sun in February 1986 and is expected back in mid-2061.

The Full Story

Halley's Comet is the only well-known short-period comet regularly visible to the naked eye from Earth and potentially seen twice in a human lifetime. English astronomer Edmond Halley realised that comets seen in 1531, 1607 and 1682 were the same object and predicted its return in 1758. He died before it reappeared on schedule, and the comet was named in his honour. Records of its appearances go back to at least 240 BC in Chinese chronicles, and it appears in the Bayeux Tapestry depicting the Norman conquest of 1066. Its next perihelion is predicted for 28 July 2061.
