(11709) Eudoxos Main-belt Asteroid
Discovered on 27 April 1998 by P. G. Comba at Prescott.
Eudoxos of Knidos (c. 408-355 B.C.) was the prime mover behind two major developments in Greek mathematical thought: the theory of proportions that overcame the crisis caused by the discovery of irrational numbers, and the method of exhaustion for the calculation of areas and volumes.Naming citation (19991123/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
