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).

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

Comet Encke is believed to be the originator of the Taurid Meteor shower ( Whipple , 1940; Klačka, 1999). Some consider the Bronze Age breakup of the originally larger comet to be responsible for ancient destruction in the Fertile Crescent , perhaps evidenced by a large Meteor crater in Iraq . The Origin Of The Swastika has also been connected with Comet Encke.

The failed CONTOUR mission was launched to study this comet, as well as Schwassmann-Wachmann 3 .
