How Big is Our Planet
Big Planets, Little Planets, Dwarf Planets,
Big Moons, Little Moons!
Earth seems to us like a pretty big place. Well, Jupiter has 317 times more mass than Earth! Saturn is 95 times as massive as Earth. But even with those giants hogging all that mass, the Sun contains 99.86% of the mass of the entire solar system!
It's a wonder there's any matter at all left over for us!
The picture below gives a better idea of how the sizes of the Sun and the planets* compare with each other. If Earth were about 2 millimeters across, as it is in this picture, the Sun would be almost 218 millimeters (about 8-1/2 inches) across!
