20362 Trilling           Discovered 1998 May 1 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
David E. Trilling (b. 1972) is an assistant astronomer at the University of Arizona. Theorist and observer, Trilling has used the Spitzer telescope to determine the diameters and albedos of NEOs, TNOs and circumstellar dust disks. He also works on theories of orbital migration and extrasolar planet formation.
