what are star's?

Stars are nothing other than suns. just like our own sun, they too are huge balls of incandescent gas,inside which "NUCLEAR FUSION" transforms hydrogen into helium.This process releases enormous amounts of energy,which is why stars shine and radiate heat.It is only because stars are so far away that they appear in the night sky as no more than tiny points of light.In reality,many stars are considerably larger than our sun.
