Artist's Illustration of the Chaotic Spin of Pluto's Moon Nix
This set of artist's illustrations of Pluto's moon Nix shows how the orientation of the moon changes unpredictably as it orbits the "double planet" Pluto-Charon. This illustration is based on dynamical models of spinning bodies in complex gravitational fields – like the field...

Artist's Animation of the Chaotic Spin of Pluto's Moon Nix
This computer animation illustrates how Pluto's moon Nix changes its spin unpredictably as it orbits the "double planet" Pluto-Charon. The view is from the surface of Pluto as the moon circles the Pluto-Charon system. This is a time-lapse view of the moon, compressing four years...
