Phaeo (minor planet designation: 322 Phaeo) is an asteroid from the central regions of the asteroid belt, approximately in diameter. It was discovered on 27 November 1891, by French astronomer Alphonse Borrelly at the Marseille Observatory in southern France. 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 – 106 Dione, 158 Koronis, 217 Eudora, and 308 Polyxo.
