"Sirius" is the brightest star system in the night sky as seen from earth. The name "Sirius" came from the Ancient Greeks meaning "Glowing" or "Scorcher". Sirius is a binary system with Sirius A being the large main-sequence star. It's small companion Sirius B is a white dwarf star. Sirius A is around 8.7 light years from the earth and is around twice the size of our sun and is 25 times more luminous than the sun. Thanks for looking, cheers, Phil
