  1. Sirius: Sirius, also known as the Dog Star, is the brightest star in the night sky and is located in the constellation Canis Major. It is about twice the size of our sun and is only 8.6 light years away from us. Sirius is referred to as a binary star system, as it has a companion star called Sirius B, which is a white dwarf.

  2. Betelgeuse: Betelgeuse is a red supergiant star located in the constellation Orion. It is approximately 640 light years away from us and is one of the largest known stars. Betelgeuse is estimated to be about 1,000 times larger than our sun and is also a variable star, meaning its brightness fluctuates.

  3. Polaris: Polaris, also known as the North Star, is a bright star located in the constellation Ursa Minor. It is approximately 430 light years away from us and is used for navigation as it appears to remain stationary in the sky while other stars rotate around it. Polaris is also a triple star system, consisting of Polaris A, Polaris B, and Polaris Ab.
