(4409) Kissling Main-belt Asteroid
Discovered on 30 June 1989 by Gilmore, A. C., Kilmartin, P. M. at Lake Tekapo.
Warwick M. Kissling (b. 1957) is an innovative applied mathematician. His computations have allowed the follow-up and recovery of several new minor planets. Like many New Zealanders, he is fond of clambering around mountains in his spare time.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
