Which constellation is known for containing the brightest star in the night sky?

Canis Major is recognized for its inclusion of Sirius, the brightest star visible from Earth. Sirius, often called the "Dog Star," is part of the Canis Major constellation, which is associated with the mythology of hunting dogs. Its brightness is notable, as it is nearly twice as luminous as the next brightest star, Canopus, and is easily visible to the naked eye. The distinct positioning of Canis Major in the sky makes it prominent in many cultures and contributes to its popularity among stargazers.

Draco, Cassiopeia, and Pegasus do not possess the same level of brightness when it comes to their stars. While they all contain stars of interest and are significant for various reasons, it is Canis Major that holds the title for the brightest, primarily due to Sirius's exceptional luminosity and location in the night sky.
