Created by the Universidad de Puerto Rico en Arecibo (the University of Puerto Rico at Arecibo) scientists, this amazing infographic shows the volumes of the oceans of the Solar System. The unit used is the volume of the liquid water on Earth, so the ocean volumes of the other planetary objects are given by the multiples of the volume of the oceans on our planet.
