Sky Map
Celectial bearing and elevation at 21:21
Physical double stars are true binary systems, where two stars are gravitationally bound and orbit a common center of mass. These systems offer insights into stellar dynamics and evolution. Well-known examples include Sirius A and B, the brightest star system in our sky, and Castor, a sextuple star system in the Gemini constellation.
