Video Title : BRIGHTEST STAR'S AT NIGHT SKY
.
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky.
.
The brightest stars in our night sky are an object of constant interest to stargazers. Some appear very bright to us because they're relatively nearby, while others look bright because they're massive and very hot, pumping out lots of radiation. Some look dim because of their age, or because they're far away. There's no way to tell just by looking at a star what its age is, but we can tell brightness and use that to learn more.
.
Stars are massive shining spheres of hot gas that exist in all galaxies across the universe. They were among the first objects to form in the infant universe, and they continue to be born in many galaxies, including our Milky Way. The star closest to us is the Sun.
.
All stars are made primarily of hydrogen, smaller amounts of helium, and traces of other elements. The stars we can see with the naked eye in the night sky all belong to the Milky Way Galaxy, the huge system of stars that contains our solar system. It contains hundreds of billions of stars, star clusters, and clouds of gas and dust (called nebulae) where stars are born.

Here are the ten brightest stars in Earth's night sky. These make excellent stargazing targets from all but the most light-polluted cities.
