(7999) Nesvorny Main-belt Asteroid
Discovered on 11 September 1986 by E. Bowell at Anderson Mesa.
Named in honor of David Nesvorný (b. 1969), a Czech dynamicist, currently at the Universidade de São Paulo, who has contributed to recent important discoveries on chaotic effects in the minor planet belt, their role in depleting resonant gaps, shaping the current belt population, and supplying Mars-crossing objects. In particular, Nesvorný has studied both analytically and numerically the effects of hitherto unstudied three-body resonances and slow, diffusion-like processes. Citation written by P. Farinella at the request of the discoverer.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
