Heavenly bodies, by their very definition, are not "in the world" - they are in the heavens - that is, they are out of this world. Heavenly bodies include the Sun, the moon, the planets of the solar system and other stars and their planets. They are - literally - too many to count.
The "world" constitutes the planet Earth. There are 8 major planets around the Sun in our solar system, and many more orbiting other stars. (see related question)
