Nu1 Columbae, Latinized from ν1 Columbae, is a star in the southern constellation of Columba. It is visible to the naked eye, having an apparent visual magnitude of 6.14.[2] According to the Bortle scale, stars with this magnitude are faintly visible from dark rural skies. Based upon an annual parallax shift of 25.40 mas,[1] this star is about 128 light years distant from the Sun.
This star has a stellar classification of F0 IV,[3] which indicates it is an evolving F-type subgiant star. It is an estimated 6410 million years of age, with a mass 1.41 times that of the Sun.[6] The star is spinning relatively rapidly, with a projected rotational velocity of 161 km/s.[3] It is radiating around 4.3[7] times the solar luminosity from its outer atmosphere at an effective temperature of 7,079 K.[6]
