Star

A star in this area means that the sky body, which is visible in the cloudy night. Because the stars are a few thousand kilometers away from the Earth, we see the stars only as a point that shines in the sky. If we speak scientific language, the star is a large gas ball, which radiates light and keeps in a suspended state of its own gravity, and also the pressure produced by thermonuclear fusion reactions.

The star consists mainly of hydrogen-helium elements. All stars have a shape of a ball, which is possible due to gravity, which under pressure does not allow to fly particles in different directions.
