17215 Slivan           Discovered 2000 Jan. 6 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Stephen M. Slivan (b. 1962) demonstrated a preferential spin-vector alignment among Koronis family members. Known as "Slivan states", the discovery has led to a new understanding of thermal radiation forces on small bodies.
