Oberon and Charon, compared

Oberon and Charon, compared
Oberon and Charon, compared Oberon, moon of Uranus (left), and Charon, moon of Pluto (right). These worlds are of similar size and both exhibit intriguing geology. Oberon was barely glimpsed by Voyager 2 as it flew by the Uranian system on January 24, 1986, while Charon received a close encounter by the New Horizons spacecraft on July 14, 2015. Charon's complex geology makes the barely-studied moons of Uranus even more tantalizing. NASA / JPL / JHUAPL / SwRI / Ted Stryk
