(10950) Albertjansen Outer Main-belt Asteroid
Discovered on 24 September 1960 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Albert Jansen (1940-2004), first director of The Hague Planetarium, was an exceptional teacher and talented experimenter. Living later in South Africa, he built a private observatory for use by advanced amateur astronomers. Shortly before his death he published Star Maps for Southern Africa, the first southern night-sky guide.Naming citation (20060413/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
