HD 48265 is the Henry Draper Catalogue designation for a star in the southern constellation Puppis. It has an apparent visual magnitude of 8.07,[2] which makes it too faint to be seen with the naked eye. Based upon parallax measurements made during the Hipparcos mission, it is located at a distance of roughly 293 light-years (90 parsecs) from Earth.[1]
This star has a stellar classification of G5IV/V,[3] suggesting that, at an age of 4.8 billion years,[5] it has reached an intermediate evolutionary stage between a main sequence star and a subgiant. It has but 93% of the mass of the Sun,[6] while its outer atmosphere has begun to expand, reaching about 2.3 times the Sun's radius.[7] HD 48265 is radiating 62%[7] of the Sun's luminosity from its atmosphere at an effective temperature of 5,508 K,[5] giving it the yellowish glow of a G-type star.[9] Measurement of the chemical abundances of this star indicate that, compared to the Sun, it has a 95%[2] greater proportion of elements other than hydrogen and helium—what astronomers term the star's metallicity.
