The star Sirius is one of our closest neighbours, only 8.7 light years away. Sirius is one of the brightest stars seen from Earth. If you draw a straight line through the three bright stars in Orion’s Belt, Sirius is the bright star down to the left. Sirius is a doublestar. The smallest companion can’t be seen by the naked eye. Sirius B’s orbit was calculated about 150 years ago. The two components are revolving about a common center of mass in about 50 years.
The Egyptians followed a ”sirius calendar” of 360 days.
The Dogons, a west African tribe, claims that their ancestors came from Sirius, and they knew about the invisible star. According to French antropologists, Sirius B was part of the Dogon mythology even before its existence was suspected among Western scientists.
