Stars are composed of gases which ignite themselves and converge in a spherical shape. Their energy is stored in a specific spherical structure depending upon their gravity. Each star has its own gravity formed by the mass of igneous gas combined to form a star.
They illuminate the cosmic area and their lights can travel much longer distances. The stars can be classified based on spectral frequency or the light they are emitting and also based on their temperature. Thus, the star with the coolest temperature is termed as Red stars and the star with the hottest temperature is termed as blue stars.
