'''Acrux''', also known as '''Alpha Crucis''', is the southernmost first magnitude star and the twelfth brightest star in the night sky, with an apparent magnitude of 0.77. The star is also the brightest star of the constellation [[Crux]], otherwise commonly known as the '''Southern Cross'''. Because of the star's location at 63 degrees south of the [[celestial equator]], it is not visible north of latitude 27°N. <ref name="david">http://www.daviddarling.info/encyclopedia/A/Acrux.html</ref> | '''Acrux''', also known as '''Alpha Crucis''', is the southernmost first magnitude star and the twelfth brightest star in the night sky, with an apparent magnitude of 0.77.
