Comet 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 the years 1786, 1795, 1805 and 1818 to the same object. He published his conclusions during the year 1819 in the journal Correspondance astronomique, and predicted correctly its return in 1822. It's official designation is 2P/Encke, which marks it as the second periodic comet discovered after Halley's Comet (aka 1P/Halley).
