Nu Eridani (ν Eri) is a star in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.93.[3] The distance to this star is roughly 520 light years, based upon an annual parallax shift of 0.00625 arcseconds.[2] If the star were 33 ly (10 pc) from the Sun, it would be the brightest star in the night sky with an apparent magnitude of −2.84.[4] (Currently, the brightest star is Sirius at magnitude −1.46.)
