Pluto and Charon are shown in enhanced color, which is the highest-resolution color image of the pair returned to Earth by New Horizons spacecraft. The images were acquired on July 13 and 14, 2015.
The image highlights the contrasting appearance of the two worlds. Pluto shows a wide variety of subtle color variations, including yellowish patches on the north polar cap and subtly contrasting colors for the two halves of Pluto’s “heart”. Charon is mostly gray, with a dark reddish polar cap.
