is a double star in the constellation Grus. With an apparent visual magnitude of 5.33,[2] it is visible to the naked eye. The annual parallax shift is 72.54 mas, which yields a distance estimate of 45 light years. It has a relatively high proper motion, traversing the celestial sphere at the rate of 93.4 mas per year,[12] and is moving closer to the Sun with a radial velocity of −13 km/s.[5] | is a double star in the constellation Grus.
