Discovered on 8 February 1994 by E. W. Elst at La Silla.
Estonian astronomer Jaan Einasto (b. 1929) discovered the presence of dark matter in the universe in 1974, and he noted the regular cell-like structure in the large scale-distribution of superclusters of galaxies in 1977. Still a very active scientist, he has written more than 250 scientific papers.Naming citation (20090209/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
