HD 48265 b is an extrasolar planet located approximately 293 light-years away in the constellation of Puppis, orbiting the 8th magnitude G-type main sequence star HD 48265. It has a minimum mass of 1.47 times that of Jupiter. Because its inclination is not known, its true mass is not known. It orbits at a distance of 1.81 AU with an orbital eccentricity of 0.08.[2][1]

As part of the NameExoWorlds project of the IAU, HD 48265 b was named "Naqaỹa" ("brother") and HD 48265 "Nosaxa" ("springtime") in the Moqoit language by Argentine respondents to an online poll.[3]
