KIC 11145123 (sometimes mistakenly called Kepler 11145123[9]), is a white hued star located in the northern constellation Cygnus, the swan. It has an apparent magnitude of 13.12,[2] making it readily visible in large telescopes, but not to the naked eye. The object is located relatively far at a distance of approximately 3,910 light years,[1] but is rapidly approaching the Solar System with a radial velocity of −136 km/s.[5]
