B-type star in the constellation Puppis

NW Puppis, also known as υ2 Puppis, is a star in the constellation Puppis. Located around 910 light-years distant, it shines with a luminosity approximately 1,108 times that of the Sun and has a surface temperature of 15,000 K.[4] Anamarija Stankov ruled this star out as a Beta Cephei variable.[6]

Neither component of this double is given a letter in Lacaille's catalogue or the British Association star catalogue.[7][8] Gould gave them the designations (Latin letter) v1 and v2 Puppis, but these are rarely used.[9] Lacaille applied the Greek letter υ to the star now called υ Carinae.[7] The designation υ2 first appeared in several catalogues at the end of the 19th century.[10]
