Star in the constellation Camelopardalis
40 Camelopardalis is a single[ 9] star in the northerncircumpolar constellation ofCamelopardalis ,[ 8] located around 600 light years distant from theSun . It is visible to the naked eye as a faint, orange-hued star with anapparent visual magnitude of 5.37. This object is moving further from the Earth with a heliocentricradial velocity of +8.6 km/s.
This is an aginggiant star with astellar classification of K3 III,[ 3] having exhausted the hydrogen at itscore andevolved away from themain sequence . It has expanded to 33 times theSun's radius and is radiating 384 times theluminosity of the Sun from its enlargedphotosphere at aneffective temperature of 4,188 K .
There is a magnitude 11.50optical companion , located at anangular separation of 104.20″ along aposition angle of 355° from 40 Camelopardalis, as of 2010.[ 10]
