}}{{Starbox end}}Nu1 Lupi (ν1 Lup) is a solitary[18] star in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 5.01.[3] It is a high proper motion star[20] with an annual parallax shift of 27.89[ mas as seen from Earth, yielding a distance estimate of 117 light years from the Sun.]
This is a two[11] billion year old evolved star with a stellar classification of F6 III-IV,[4] indicating that the spectrum has characteristics intermediate between a subgiant and giant star. It is most likely the source of X-ray emission[20] detected at these coordinates with a luminosity of {{Val|1.09e29|u=erg s−1}}.[25] The star has an estimated 1.67[11] times the mass of the Sun and is spinning slowly with a projected rotational velocity of 2.8 km/s.[10]
