Procyon is the seventh brightest star in the sky and one of the vertices of the Winter Triangle. It's one of our nearest neighbors at just over 11 light years away in the constellation Canis Minor. Procyon is a binary star system, composed of a white main sequence star and a white dwarf star.
Artist's impression of brown dwarf ULAS J222711-004547, which has a very thick cloud layer of mineral dust. The dust is making the brown dwarf appear redder than its counterparts. Credit: Neil J. Cook, Centre for Astrophysics Research, University of Hertfordshire
