(405571) Erdospal Mars-crossing Asteroid
Discovered on 31 August 2005 by Z. Kuli K. Sárneczky at Piszkesteto.
Pál Erdős (1913–1996) was a Hungarian mathematician, much of whose work centered around discrete mathematics. His work leaned towards solving previously open problems, rather than developing or exploring new areas of mathematics. He published around 1500 mathematical papers during his lifetime.Naming citation (WGSBN Bull. 1, #1, 29), IAU / Minor Planet Center, via NASA/JPL
