Animation illustrating orbits of Pluto, Charon, Nix, and Hydra about the system's barycenter. Derived from two Hubble Space Telescope images and a diagram of the orbits.
Names orbit with bodies.
Reprojected plane of orbits to face-on view, determined angles swept in the three days separating original images, made new frames based on date/angle. Each time step represents one Earth day.
