Crux Crux Crux is a constellation located in the southern sky in a bright portion of the Milky Way. It is among the most easily distinguished constellations, as all of its four main stars have an apparent visual magnitude brighter than +2.8, even though it is the smallest of all 88 modern constellations. Its name is Latin for cross, and it is dominated by a cross-shaped or kite-like asterism that is commonly known as the Southern Cross. Predominating is the first-magnitude blue-white star of Alpha Crucis or Acrux, being the constellation's brightest and most southerly member. Crux is followed by four
Carina (constellation) in Carina. One is known as the 'Diamond Cross', which is larger than the Southern Cross (but fainter), and, from the perspective of the southern hemisphere viewer, upside down, the long axes of the two crosses being close to parallel. Another asterism in the constellation is the False Cross, often mistaken for the Southern Cross, which is an asterism in Crux. The False Cross consists of two stars in Carina, Iota Carinae and Epsilon Carinae, and two stars in Vela, Kappa Velorum and Delta Velorum. Carina is known for its namesake nebula, NGC 3372, discovered by French astronomer Nicolas Louis
