How Many Earths Can Fit Inside Every Planet? (3D Comparison)

How Many Earths Can Fit Inside Every Planet? And how many Earths can fit inside the giant worlds of our Solar System? In this 3D size comparison, we put every major world of the Solar System to the test. Starting with dwarf planets and moons smaller than Earth, we see how many of them can fit inside our planet. Then we reverse the challenge and find out how many Earths can fit inside the larger planets, all the way up to Jupiter and the Sun. Unlike most comparisons, this video shows both the ideal result based on volume and the actual result based on real sphere packing, revealing how much empty space appears when spheres are packed together.
