10 Ursae Majoris
The name of this F-type binary star is something of an historical accident. Centuries ago, it belonged to the constellation of the Great Bear, as the designation Ursae Majoris suggests. In 1690, though, it was transferred by Hevelius into Lynx, where it remains to this day. For some reason, though, its 'Great Bear' name has, almost uniquely, survived for more than three hundred years.
