Details

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Gamma Crucis, often called Gacrux, is a red giant star approximately 88 light-years away in the constellation of Crux. Among Portuguese-speaking peoples it is also named "Rubídea", in reference to its color. The star is the third-brightest star in Crux 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. Gamma Crucis is a double star, 88 light years distant from Earth. The main star is of apparent magnitude +1.6 and spectral classification M4 III. Its +6.4 magnitude white companion star lies about 2 arcminutes away at an angle of 128 degrees from the main star, and can be observed with binoculars.
