HD 45364 is a star in the southern constellation of Canis Major. It is too faint to be visible to the naked eye, having an apparent visual magnitude of 8.08.[2] The distance to this system is 112 light years based on parallax.[1] It is drifting further away from the Sun with a radial velocity of +16.4 km/s,[1] having come within 49 light-years some 1.5 million years ago.[2]
This object is an ordinary G-type main-sequence star with a stellar classification of G8V,[3] which indicates it is generating energy through core hydrogen fusion. It is around 3.4 billion years old and is spinning with a projected rotational velocity of 1.7 km/s.[5] The star has 88% of the mass of the Sun and 82% of the Sun's radius. It is radiating 56% of the luminosity of the Sun from its photosphere at an effective temperature of 5,540 K. As of August 2008 there are two confirmed extrasolar planets (or exoplanets) orbiting around it.[7]
