The boundaries of Crux are defined by its four brightest stars, which form the spine and the crossbar of the southern cross as defined by star catalogs and the official boundaries of the IAU constellations. The four defining stars of Crux are Acrux (Alpha Crucis), Mimosa (Beta Crucis), Gacrux (Gamma Crucis), and Imai (Delta Crucis).
The Southern Cross, or Crux, is the smallest of the 88 official constellations, but it is also the most distinctive.
In fact, the cross asterism that most people know and love actually contains a fifth star, Ginan (Epsilon Crucis). This star is located just below the crossbar and is actually less bright than the other four stars, but it fits nicely into the shape of the cross.
This notion of the fifth star appearing is so common that you will even notice it on the national flags of several countries. Consider Australia, Papua New Guinea, Samoa, and Brazil – all of their flags feature five stars to represent the Southern Cross, while New Zealand features four. This is a real-world application that demonstrates that “five stars” is an acceptable and correct response.
When discussing the general cross pattern → Four stars
When discussing the famous constellation design → Five stars
In most general knowledge tests, the response that most people will accept is: (d) Four Stars
