W Ursae Majoris is the prototype of a class of contact binary variable stars, and ranges between 7. 75 < sup > m </ sup > and 8. 48 < sup > m </ sup >.

Almost all known contact binary systems are eclipsing binaries ; eclipsing contact binaries are known as W Ursae Majoris variables, after their type star, W Ursae Majoris.

W Ursae Majoris ( W UMa ) is the variable star designation for a binary star system in the northern circumpolar constellation of Ursa Major.
