On July 14, the NASA spacecraft will have just one chance to get a glimpse of Pluto and its five moons—two of which were discovered after New Horizons left Earth. Those two are the dwarf planet’s tiniest moons: Styx is between 4 and 13 miles in diameter; Kerebos is between 6 and 20 miles wide. The spacecraft’s powerful Long Range Reconnaissance Imager (LORRI) photographed them at a distance of 55 million miles, after imaging giant moon Charon in 2013, and moons Hydra and Nix in 2014. Read about New Horizon’s mission in Pluto at Last.
