The next time someone asks you where the biggest ocean is, point them toward Jupiter.
While Earth harbors about 320 million cubic miles of water, our planet is practically a desert compared to the rest of the solar system.
A moon of Jupiter called Europa, for example, which is roughly the size of our own moon, likely hides a subsurface ocean with more than twice as much water as there is on Earth. Yet even that pales in comparison to Europa's neighbor Ganymede; more than 30 times as much water as our home planet is thought to reside there as liquid and ice.
To see just how Earth stacks up against other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA's Jet Propulsion Laboratory who's calculated how much water might be out there.
The to-scale graphic below uses Vance's data to show the plausible volumes of water (both liquid and ice) for the nine verified and suspected ocean worlds so far:
