Overall, there are as many as an estimated 1×1024 stars (more stars than all the grains of sand on planet Earth). While it is often believed that stars only exist within galaxies, intergalactic stars have been discovered. A multi-star system consists of two or more gravitationally bound stars that orbit each other.

Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
