NV Puppis (NV Pup), also known as υ1 Puppis, is a class B2V[3] (blue main-sequence) star in the constellation Puppis. Its apparent magnitude is 4.67[2] and it is approximately 800 light years away based on parallax.[1]

A light curve for NV Puppis, plotted from Hipparcos data[13]

It is a γ Cas variable, ranging from 4.78 to 4.58 magnitude.[4] It is most likely an optical double with the nearby NW Puppis.[14]

Neither component of this double is given a letter in Lacaille's catalogue or the British Association star catalogue.[15][16] Gould gave them the designations (Latin letter) v1 and v2 Puppis, but these are rarely used.[17] Lacaille applied the Greek letter υ to the star now called υ Carinae.[15] The designation υ1 first appeared in several catalogues at the end of the 19th century.[18]
