Rho Puppis (ρ Puppis, abbreviated Rho Pup, ρ Pup), formally named Tureis /ˈtjʊəreɪs/,[13] is a star in the southern constellation of Puppis. With an average apparent visual magnitude of 2.78,[2] it is the third-brightest member of this generally faint constellation. Based upon parallax measurements made during the Hipparcos mission, Rho Puppis is located at a distance of 63.5 light-years (19.5 parsecs) from the Sun.[1] It is the prototype of the Rho Puppis class of evolved Am stars.
