Gamma Crucis (γ Crucis, abbreviated Gamma Cru, γ Cru), also named Gacrux, is the nearest red giant star to the Sun. The distance to Gacrux has been determined using parallax measurements made during the Hipparcos mission, which yielded a value of 88.6 light-years (27.2 parsecs) away from the Sun. With an apparent visual magnitude of +1.63, this is the third-brightest star in the southern circumpolar constellation of Crux, the Southern Cross, and one of the brightest stars in the night sky. A line from the two "Pointers", Alpha Centauri through Beta Centauri, leads to within a few degrees of this star.
