It is true that planets are true children of the stars.But to become a star few criterias has to be satisfied. First thing is size.The bigger the size,the greater the gravity at the center & that much is the force of compaction as well as density to produce heat at its central core.A critical heat that would be sufficient to cause thermonuclear fusion reaction to occur.Only then some one might realize that a true star is born.Aut planets with lesser body size & cold interior ,we just can't expect it to become a star.
