It is more familiar to most observers in the northern hemisphere as the lower-left star forming the bowl of the Big Dipper, together with Dubhe, Merak and Megrez. Along with four other stars in this well-known asterism, Phecda forms an actual loose, open cluster of stars known as the Ursa Major moving group. Like the other stars in the cluster, it is an average main sequence star not unlike our Sun, although somewhat hotter, brighter and larger.
