HD 50499 is a star in the constellation of constellation of Puppis. With an apparent visual magnitude of 7.21, this star is too faint to be in naked eye visibility. It is located at a distance of 151 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +36.7 km/s.
This object is a G-type main-sequence star with a stellar classification of G0/2 V. It is positioned 0.6 magnitudes above the main sequence, which may be explained by a high metallicity and an older age. Vogt et al. (2005) estimated its age as about 6.2 billion years, although more recent estimates give a younger age of around 2.4 billion years. The star has 1.31 times the mass of the Sun and 1.42 times the Sun's radius. It is radiating 2.38 times the luminosity of the Sun from its photosphere at an effective temperature of 6,099 K. As of 2019, two exoplanets have been confirmed to be orbiting the star.
