Sirius has an apparent magnitude of -1.5 and Canopus has an apparent magnitude of -0.7. Sirius is _2 times.brighter than Canopus when seen from Earthprobably father away from Earth than Canopusmuch larger and more massive than Canopusan O class star, while Canopus is an M class

Explanation:

With an apparent visual magnitude of -1.5, the brightest star observed in the night sky is Sirius and hence it is about twice as the second brightest star in the night sky, Canopus.

Sirius, which is a binary star, meaning it consists of a main star and another star (a dwarf), derives its brightness from its close proximity to our solar system and also due to its own inherent luminosity.

It is located at about 8.6 light years away from earth and for the next 210,000 will remain the brightest star in the night sky.
