(11881) Mirstation Main-belt Asteroid
Discovered on 20 August 1990 by E. W. Elst at La Silla.
The Russian space station Mir, launched in 1986, remained in service for more than 15 years as a laboratory for a wealth of scientific experiments performed on board by international crews. Mir was destroyed in March 2001 in order to avoid an uncontrolled return into the earth's atmosphere.Naming citation (20010509/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
