NotesTogether with Alpha Centauri, its near neighbour in the sky, Hadar forms the Southern Pointers, which can be used to locate the constellation Crux as well as the Southern Celestial Pole.

This fairly bright star appears to lie close to Alpha Centauri (or Rigil Kentaurus) in the sky. In fact, though, it is more than a hundred times further away from Earth than its better-known neighbour.
