Remarks: Sirius can be observed from all the regions inhabited by Earth and, in the Northern Hemisphere, is one of the tops of the Astronomy of the Winter Triangle. It looks like a bright star of a marked white-blue color; although it is in the southern hemisphere, it is close enough to the heavenly equator to be visible even at very north latitudes.
Curiosity: In many cultures, the star has often been associated with the shape of a dog. The Greeks thought that its glitter at its elixir could damage crops, lead to severe drought or even cause and spread angry epidemics; its name derives from ancient Greek Σείριος  (pronounced Séirios), which means shining, but also burning, burning. The Romans used to sacrifice a dog together with a sheep and wine, in order to prevent the harmful effects of this star. The days when these ceremonies were consumed, at the beginning of the summer, were known as the Dog Days, and the star Sirio Stella Canicula.
