(9836) Aarseth Main-belt Asteroid
Discovered on 15 October 1985 by E. Bowell at Anderson Mesa.
Norwegian-born astronomer Sverre J. Aarseth (b. 1934), of the Institute of Astronomy, Cambridge, developed a unique set of n-body codes and used them for studying gravitational systems, such as globular clusters and merging galaxies, where encounters and collisions are important. The name was suggested by E. M. Standish.Naming citation (20010705/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
