Sam the Dog Star


Sirius is the ‘Dog Star’ in the constellation Canis Major (the big dog). It is the brightest star in the night sky at a magnitude of almost -2. It’s so bright due to its nearness to earth (only 8.6 light years), because it has twice the mass of the Sun and is 23 times more luminous.
