first glance, Earth seems like the ultimate water world…

But gather every drop of water on our planet — every ocean, sea, river, glacier, and cloud — and it would form a sphere just 1,385 km wide.

Now look at Ganymede.

This icy moon of Jupiter hides a vast ocean beneath its frozen surface… and if you collected all of its water?

You’d get a sphere 4,074 km across — nearly three times larger than Earth’s.

Let that sink in.

💧 More water than Earth… on a moon, orbiting a gas giant, in the cold outer Solar System.
