212 Medea is a very large main-belt asteroid that was discovered by Johann Palisa on February 6, 1880, in Pola, and was named after Medea, a figure in Greek mythology.[5]
Photometric observations of this asteroid in 1987 gave an incomplete lightcurve with a period of 10.12 ± 0.06 hours and a brightness variation of 0.13 in magnitude. This object has a spectrum that matches a DCX: classification.[4] Lightcurve data has also been recorded by observers at the Antelope Hill Observatory (H09), which has been designated as an official observatory by the Minor Planet Center. They found a period of 10.283 hours with a brightness variation of 0.08 magnitude.[6]
