Hello My Dear Friend!
Do you mean Sun or actually Moon?
If Moon is what you're looking for...then that is absolutely IMPOSSIBLE, due to that the Earth is WAY bigger than the Moon, therefore, not even HALF of the Earth would fit into the Moon since it's too small XD.
But if it's Sun...well then, the Answer is that it would take 1.3 million Earths to fill up the Sun. That's a lot of Earths LOL XD
