Great Comet of 371 BC

The Great Comet of 372–371 BC (sometimes Aristotle's Comet) was a comet that is thought to possibly be the source of the Kreutz sungrazer family.

The Great Comet was observed by Aristotle, Ephorus, and Callisthenes. Ephorus reported that it split into two pieces, a larger fragment that is thought to have possibly returned in 1106 AD, as X/1106 C1, and another smaller fragment. While visible from Earth, it was said to have cast shadows at night comparable to a full moon.
