HD 64307, also known as HR 3075, is a solitary, orange hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.35, allowing it to be faintly seen with the naked eye. Based on parallax measurements from the Gaia spacecraft, The object is estimated to be 690 light years distant. It appears to be receding from the Sun, having a heliocentric radial velocity of 34 km/s.
HD 64307 is an evolved star with a stellar classification of K3 III. Gaia DR3 stellar evolution models place it on the red giant branch. It has a mass comparable to the Sun but due to its evolved state, it has an enlarged radius of 49.9 R☉. It shines with a bolometric luminosity of 892 L☉ from its photosphere at an effective temperature of 4,264 K. HD 64307 has an iron abundance 80% that of the Sun, and is also lithium enriched. Like most giant stars, the object spins slowly, having a projected rotational velocity lower than 2 km/s.
