Beta Canis Minoris is a hot, B8-class main sequence star of apparent magnitude 2.9, easily visible to the naked eye. It is slightly variable, and belongs Gamma Cassiopeiae category of variable stars. This star is rotating rapidly and is surrounded by a disk of material, which the emissions are heating up.

The traditional name is supposed to be from an Arabic word al-ghumaisa’ "the bleary-eyed one", cognate with the modern Arabic name for Procyon, غموص ghumūş.
