Hadar

Hadar is a blue giant (spectral type B1III) about 390 light-years away. With an apparent magnitude of 0.61 it is a very bright, conspicuous star.

The second-brightest star in Centaurus. Together with Rigil Kentaurus it points to the Southern Cross.

Its light output is roughly 7,000 times that of the Sun (a rough estimate in visible light, calculated from brightness and distance).

It is never visible from Germany, as it lies too far south.
