Becrux

Becrux (β Cru / β Crucis / Beta Crucis) is the second brightest star in the constellation Crux and one of the one of the brightest stars in the nighttime sky.

Since Beta Crucis is at roughly −60° declination, it is only visible south of the Tropic of Cancer and therefore didn't receive an ancient traditional name; "Becrux" is simply a combination of the "Be" in Beta plus Crux. Sometimes it is also called Mimosa.

Beta Crucis is located approximately 353 light years from Earth's Solar System.
