This animation of Pluto and its largest moon, Charon, was taken by New Horizons spacecraft as it traveled toward Pluto in July 2014. Covering almost one full rotation of Charon around Pluto, the 12 images that make up the movie were taken July 19-24 with the Long Range Reconnaissance Imager (LORRI) at distances ranging from about 429 million to 422 million kilometers.
