Sun and stars
A star is called sun when we partucalarly talk about a solar system. A star is not just a sphere made up of hot plasm. It is the source of green energy produced by the process of nuclear fusion occuring between hydrogen atom on it. Suns are the centers of there respective solar systems. Its revolving plasma creates a magnetic field and its huge size genrates gravitational field which holds together a solar system. Life time of solar system depends upon its sun's life.
A sun dominates the whole solar system. A solar system starts with the birth of sun in nebula and ends with its death. It holds together matter in solar system. Help planest to have atmosphere. Provides conditions to grow life on planets. Nothing more is important then a sun in a solar system. There are billions and billions of stars in universe from which there are mainly four types of star F(blue to white),G(white to yellow),K(orange to red) and M(red) having approximate surface temperature of 6000-7500K,6000-5000K,5000-3500K and 3500K respectively. where F type have least life time where M type have maximum life time.They are like cells of a body(glaxy).
