Name source

Sirius's English common name is Sirius, which comes from the Greek σ ε? ριο? It means "burning", because the ancients thought it was summer when Sirius and the sun rose at the same time, and the combination of Sirius's light and the sun's light was the reason for the hot weather in summer. This ancient Greek word may have developed from somewhere before the ancient Greek period.

The earliest discovery of this name can be traced back to hesiod's poem Work and Time in the 7th century BC. The ancient Greeks called summer "dog day", because only dogs would run out like crazy in such hot weather, so this star was also called "dog star". The ancient Egyptians called Sirius Sothis, which means "the star on the water".
