8 Camelopardalis is a star in the northern circumpolar constellation of Camelopardalis.[7] It is a challenge to view with the naked eye, appearing as a dim, orange-hued star with an apparent visual magnitude of 6.09.[2] Based upon parallax, it is located around 750 light years away from the Sun.[1] At that distance, the visual magnitude is diminished by an extinction of 0.58 due to interstellar dust.[8]

This is an aging K-type giant star with a stellar classification of K4 III,[4] which indicates it has exhausted the hydrogen at its core and evolved away from the main sequence. The star has expanded to 30[3] times the radius of the Sun and is radiating 341[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,257 K.[1]
