Answer:
Sirius is a binary star dominated by a luminous main sequence star, Sirius A, with an apparent magnitude of -1.46. Sirius A's apparent brightness can be attributed both to its inherent luminosity, 20 times that of the Sun, and its proximity. At just 8.7 light years away, Sirius is the seventh closest star to Earth.
