Sirius

Sirius, often called the Dog Star, is the brightest star in the night sky and is part of the constellation Canis Major. Located about 8.6 light-years from Earth, it shines noticeably due to its intrinsic brightness and proximity to us. Sirius is actually a binary star system, consisting of two stars: Sirius A, a main-sequence star, and Sirius B, a white dwarf. Ancient cultures revered Sirius, linking it to agricultural cycles and mythology. Its appearance in the sky often signals the onset of summer in various traditions, earning it significant historical and cultural importance.
