Plutão


"“We see Pluto in these images about as well as we see the Moon with the naked eye. Now imagine the Moon changing by that much in such a short period of time. If we look around the Solar System at the surfaces we can observe, we see changes to the ice caps of Earth and Mars and that’s about it. But Pluto offers up more dramatic changes than anything else. There’s a good reason for this: The Kuiper belt features objects in extreme orbits. Right now it’s in the spring of its year, but by 2108 it will be at its furthest from the Sun. Pluto in winter will be a colder place on which things will freeze out and re-condense.”"
