On: All of Earth's water in a single sphere (2019)

[ceejayoz]

It would use up roughly the same volume, but it'd be a lot more water.

(Much heavier, I suspect, as well.)

[rachofsunshine → ceejayoz]

Much lighter, actually. Ceres isn't particularly dense as rocky bodies go (~2.2 g/cm^3, give or take), but it's still much denser than water (~1 g/cm^3).
