17060 Mikecombi           Discovered 1999 Apr. 9 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Michael R. Combi (b. 1962), of the University of Michigan, is a planetary astronomer who specializes in the detailed modeling of cometary comae. His model for the distribution of water molecules and associated byproducts has been invaluable in understanding a wide variety of coma observations.
