> "The amount of water in all the Earth's oceans is a miniscule proportion of the amount of water in the solar system, though" Not only in proportion to the entire solar system, but also just in the context of our own planet. We think of Earth as a wet place because we keep hearing that two-thirds of the surface is covered in the stuff. But it's an incredibly thin coat. At its deepest points the ocean is what, eleven kilometers deep? From there it's another six thousand kilometers to the core. We're more a rock with a thin sheen of water than we are appreciably 'wet'.
