Pluto Quiz Questions

The Pluto-Charon system.

The Pluto-Charon system. Charon’s orbit around Pluto is shown in green. Pluto’s orbit around the Pluto-Charon system barycentre is shown in red. This shows that Pluto orbits a point outside itself. This is why Pluto and Charon are sometimes considered to be a double dwarf planet. The two small satellites of the Pluto-Charon system, Nix and Hydra, are not shown (they are on the other side).

Artist’s impression of how the surface of Pluto might look

Artist’s impression of how the surface of Pluto might look, according to one of the two models that a team of astronomers has developed to account for the observed properties of Pluto’s atmosphere, as studied with CRIRES. The image shows patches of pure methane on the surface. At the distance of Pluto, the Sun appears about 1000 times fainter than on Earth. (Photo credit: Wikipedia)
