Chacornac's Comet, formally designated as C/1852 K1, is a faint parabolic comet that was observed through telescopes between May and June 1852. It is the only comet discovered by French astronomer, Jean Chacornac, and is the parent body of the Eta Eridanids meteor shower.

Discovery and observations

Jean Chacornac made his only comet discovery from the Marseille Observatory on 16 May 1852, where he spotted a "faint, diffuse object" without a discernible tail nor nucleus on the constellation Cepheus. He later confirmed his discovery the following day.

Notes

  1. Alternatively, the periodic comet 273P/Pons–Gambart is also considered as the parent body of the Eta Eridanids. However, recent evidence suggests that C/1852 K1 (Charconac) is the much more likely candidate from where this meteor shower originated.
  2. Reported initial position upon discovery was: α = 22 34 , δ = 66° 00′
