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.
[7] It radiates 12 times the luminosity of the Sun from its photosphere at an effective temperature of 7,590 K.[8] Unlike most hot stars, KIC 11145123 spins exceptionally slowly with a projected rotational velocity of 1 km/s.
[10][6] KIC 11145123 is currently believed be the roundest natural object, with the difference between equatorial and polar radii equaling a mere three kilometers.
