Introduction[]
An oceania, aquaplanet or water world is a type of exoplanet wherein the surface is completely covered by water, and a substantial portion of its mass is water. During planet formation it occurs that icy planets move inward (i.e., toward the star) as they form. Inward migration presents the possibility that they move to orbits where their ice melts into liquid form, turning them into ocean planets. In some oceaniae more than 10% of the total planetary mass is water. These planets have oceans hundreds of kilometres deep. Their abyssal depths are so deep and dense that even at high temperatures the pressure turns the water into ice. Smaller ocean planets have less dense atmospheres and lower gravity; thus, liquid can evaporate much more easily than on more massive ocean planets. Such planets have higher waves than their more massive counterparts due to their lower gravity.
