What is Sadachbia
Sadachbia, gamma Aquarii, bears in Arabic the name 'the lucky star of tents': it announced the arrival of spring and, with it, the moment when nomadic peoples pitched their camps in the south of the Arabian Peninsula. White and A-class at 164 light-years, she forms a small Y of four stars that was the figurative heart of the celestial water-bearer.
