HD 48265, also named Nosaxa, is a star in the southern constellation Puppis. It has an apparent visual magnitude of 8.07, which makes it too faint to be seen with the naked eye. Based upon parallax measurements made during the Gaia mission, it is located at a distance of 296 light-years (91 parsecs) from Earth. It hosts two known planets, HD 48265 b and c.This star appears close in the sky to Canopus, the second-brightest star in earth's sky, and is also a similar distance away. Because of this Canopus is the brightest star in the sky of Nosaxa's planets (other than Nosaxa itself), and, at magnitude -5.87 would appear far brighter than any star or planet seen from earth.
