10370 Hylonome           Discovered 1995 Feb. 27 by D. C. Jewitt and J. X. Luu at Mauna Kea.
Fairest of all the female centaurs, the beautiful and civilized Hylonome was in love with the handsome Cyllaros, who was accidentally killed by a javelin, thrown at a wedding. On witnessing this, Hylonome threw herself on the javelin and died.
