349 Dembowska

349 Dembowska is an asteroid that is very red in color and of a unique type (R); it was discovered in 1892 by the French astronomer August Charlois. Dembowska is highly irregular in shape, spins around 5 times a day, and has a surface made up largely of the bright green mineral, olivine. Its composition seems closely to match that of the pyroxene-olivine achondrite meteorites.
