The Moon looks huge in the night sky, and next to Earth, it doesn’t seem that small either.
Its diameter is only about 3.7 times smaller than Earth’s:
Earth - 12,742 km
Moon - 3,474 km
But size becomes deceptive when volume enters the picture.
Earth is not just slightly larger - it has about 49 times more volume than the Moon and is about 81 times more massive. That’s why, once you start thinking in three dimensions, the difference suddenly feels enormous.
In fact, nearly 50 Moons could fit inside Earth.
That’s the strange thing about space - small differences in diameter turn into gigantic differences in volume.
