- Located about 321 light-years from Earth, Acrux is actually a binary system consisting of two nearly identical B-class stars.
- To see Acrux and the Southern Cross, one needs to be south of about 27 degrees north latitude and ideally even farther south for better visibility.
- Acrux appears as a single star to the naked eye, but in a small telescope, it can be resolved into two stars.
- The Southern Cross can only be seen from the Southern Hemisphere, and its visibility improves the farther south you are on the globe.
- The star Acrux serves as the bottom marker of the Southern Cross constellation, and is visible every night of the year from locations around 27 degrees south latitude.
- Acrux is a subgiant star that is hotter, brighter, larger, and more massive than the Sun, and it will eventually evolve into a white dwarf star.
- The Southern Cross has historical significance, with images of it appearing on flags of various nations and provinces in the Southern Hemisphere.
- Despite the Southern Cross not exactly resembling a cross, it holds cultural importance and is well-known among those in the Southern Hemisphere.
