NV Puppis

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

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

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