12153 Conon           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Conon of Samos (c. 280-c. 220 B.C.) was a Hellenistic astronomer and mathematician who worked in Alexandria. In 246 B.C. he created the constellation of Coma Berenices, commemorating the sacrifice of Queen Berenice's tresses of hair after her husband's return from the Third Syrian War.
