(6081) Cloutis Main-belt Asteroid
Discovered on 2 March 1981 by S. J. Bus at Siding Spring.
Edward Cloutis (b. 1958), professor at the University of Winnipeg, studies the spectra of mineral assemblages similar to those found on planetary surfaces. He was the first to derive a relationship between the olivine-orthopyroxene fraction and the ratio of silicate absorption bands in reflectance spectra.Naming citation (20020624/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
