Full Answer

Sirius is actually a binary star; its companion is a white dwarf near the size of the sun called Sirius B. The recording of Sirius dates back to at least ancient Egypt, where it was known as "Sopdet" and was a major feature of the Egyptian calendar. Its first annual heliacal rising signaled the beginning of the flood season for the Nile River Delta.
