322 Phaeo is an asteroid from the central regions of the asteroid belt, approximately 70 kilometers (43 miles) in diameter. It was discovered on 27 November 1891, by French astronomer Alphonse Borrelly at the Marseille Observatory in southern France.[1] The presumably metallic X-type asteroid is the principal body of the Phaeo family and has a rotation period of 17.6 hours. It was named for the Greek mythological figure Phaeo, one of the Hyades or nymphs. Several other asteroids were named for other of the Hyades – 193 Ambrosia, 158 Koronis, 217 Eudora, and 308 Polyxo.[10]
