Nu1 Lupi (ν1 Lup) is a solitary [7] star in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 5.01. [2] It is a high proper motion star [8] with an annual parallax shift of 27.89 [1] mas as seen from Earth, yielding a distance estimate of 117 light years from the Sun.
This is a two [5] billion year old evolved star with a stellar classification of F6 III-IV, [3] indicating that the spectrum has characteristics intermediate between a subgiant and giant star. It is most likely the source of X-ray emission [8] detected at these coordinates with a luminosity of 1.09×1029 erg s−1. [9] The star has an estimated 1.67 [5] times the mass of the Sun and is spinning slowly with a projected rotational velocity of 2.8 km/s. [4]
