Comet Encke (officially designated 2P/Encke) is a periodic comet, named after Johann Franz Encke, who through laborious study of its orbit and many calculations was able to link multiple observations in 1786 (2P/1786 B1), 1795 (2P/1795 V1), 1805 (2P/1805 U1) and 1818 (2P/1818 W1) to the same object. In 1819 he published his conclusions in the journal Correspondance astronomique, and predicted correctly its return in 1822 (2P/1822 L1). Image File history File links Comet2PEncke. ...

As its official designation implies, Encke's Comet was the second periodic comet discovered after Halley's Comet (a.k.a. 1P/Halley). It is unusual in that it was named after the person who calculated its orbit rather than the person who discovered it (Pierre Méchain).

Some consider the Bronze Age breakup of an originally larger comet of which Comet Encke is a member to be responsible for ancient destruction in the Fertile Crescent, perhaps evidenced by a large (unconfirmed) meteor crater in Iraq (Identified as Umm al Biinni lake [1]). The origin of the swastika has also been connected with Comet Encke. The Bronze Age collapse is the name of the period of history of the Ancient Middle East extending between the collapse of the Hittite and Egyptian Empires in Anatolia, Syria and Palestine between 1206 and 1150 BCE, down to the rise of settled Aramaean kingdoms of the mid 10th century...

Meteor Showers

Comet Encke is believed to be the originator of several related meteor showers - the Taurids, which are encountered as the Northern and Southern Taurids across November, and the Beta Taurids, in late June and early July[2]. (See also Whipple, 1940; Klačka, 1999).
