The shine of the stars

Let’s begin by explaining to you what a star is?

A star is a massive gas ball, radiating light and held in equilibrium by its own gravity and internal pressure, in the depths of which thermonuclear fusion reactions take place (or have occurred). The star nearest to Earth is the Sun – a typical representative of the spectral class G.

To give a clear explanation for you, dear children, we must tell you about the composition of the stars. If simply, it is a round glowing plasma. It is so hot that it is even difficult for us to imagine this temperature. The surface of a star, like our Sun, is cooler (5800 Kelvin) than its core (15 million Kelvin).
