Explanation

Sirius, also known as the Dog Star, is the brightest star in Earth's night sky with an apparent magnitude of -1.46. It appears bright due to both its intrinsic luminosity (25 times more luminous than the Sun) and its relative proximity at 8.6 light-years. Sirius is part of the constellation Canis Major and is easily visible in winter skies.
