The next time you experience the day that just won't end, be thankful you're not experiencing it on Pluto. One day on the dwarf planet takes 6.4 Earth days, and its largest moon Charon also does a full rotation in the same amount of time. This week, NASA released collages showing the full rotations of Pluto and Charon, providing a multi-faced view of the planetary system.
The images in the collages were taken by NASA's New Horizons spacecraft between July 7th and 13th, as the spacecraft prepared to fly by Pluto. During that time, New Horizons went from 5 million miles away from Pluto to just 400,000 miles away. The probe snapped the pictures using its Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera. The photos show the not often seen "far side" hemispheres of Pluto and Charon.
