Jean Chacornac (21 June 1823 – 6 September 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, 1856 and in 1863. The asteroid 1622 Chacornac and the lunar crater Chacornac are named in his honour.[3]
