The answer is zero. According to www.nineplanets.org, the radius of Jupiter is 71,492 km as compared to the sun's radius of 697,000 km. This means that inside the Sun, you could probably jam in about 926 Jupiters.
The Earth is larger than the moon, and therefore only a fraction (1/50) of the Earth would theoretically "fit" inside the space of the moon. Therefore, 50 moons could fit inside the Earth.
Jupiters size was estimated long before space ships.
Theoretically silver 47 would have no neutrons but it does not exist.
