(54522) Menaechmus Main-belt Asteroid
Discovered on 23 August 2000 by S. Sposetti at Gnosca.
The Greek mathematician Menaechmus (c. 380-320 B.C.) is credited with the discovery that the ellipse, parabola and hyperbola are sections of a cone. He made his discoveries on conic sections while he was attempting to solve the problem of duplicating the cube.Naming citation (20070926/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
