Charon Makes Its Debut

Charon is the largest of Pluto’s five moons. Once thought to be a uniform ball of ice, images taken by NASA’s New Horizons spacecraft during its July 2015 flyby of the Pluto system reveal a varied world with surprising features. Dark compounds, believed to be frozen wisps of atmosphere from Pluto, blanket Charon’s northern pole. Running across Charon’s surface are cracks stretching at least 1,000 miles, including a chasm deeper than the Grand Canyon. What’s more, the moon may not even be a moon. Charon and Pluto tango around a center of mass that lies in space between them, like two ends of a lopsided dumbbell. The irregular orbits have some scientists calling the bodies a double planet. Explore the video and images to learn more.
