As an expert in astronomy, I can provide you with a comprehensive definition of Sirius. Sirius is the brightest star in the Earth's night sky. It is a binary star system, located in the constellation Canis Major. The system consists of two main components: Sirius A, which is a main-sequence star about twice as massive as our Sun, and Sirius B, which is a white dwarf that is roughly the size of Earth. Sirius A is often referred to as the Dog Star because of its prominence in the night sky and its association with the constellation. The name "Sirius" is derived from the Greek word "Seirios," which means "glowing" or "scorching."
