Jean Chacornac (June 21, 1823 – September 23, 1873) was a French astronomer and discoverer of a comet and several asteroids.[2][3]

He was born in Lyon and died in Saint-Jean-en-Royans, southeastern France. Working in Marseille and Paris, he discovered six asteroids in the asteroid belt (see table) and C/1852 K1 (Chacornac), a parabolic comet in 1852.[4] This comet is thought to be the source of the current Eta Eridanids meteors.[5] He also independently discovered 20 Massalia, which discovery is credited to the Italian astronomer Annibale de Gasparis, however.[6]

Jean Chacornac was awarded the Lalande Prize in 1855 and 1856. The asteroid 1622 Chacornac and the lunar crater Chacornac are named in his honour.[3]
