Title:
Uranus's Moon Oberon: Impact World
Explanation:
Oberon is the most distant and second largest moon of Uranus. Discovered by William Herschel [ http://www.adventur…] in 1787, the properties of the world remained relatively unknown until the robot spacecraft Voyager [ http://vraptor.jpl.…] 2 passed it during its flyby of Uranus [ http://antwrp.gsfc.…] in January 1986. Compared to Uranus' moons Ariel [ http://antwrp.gsfc.…], Titania [ http://antwrp.gsfc.…], and Miranda [ http://antwrp.gsfc.…], Oberon [ http://seds.lpl.ari…] is heavily cratered, and in this way resembles Umbriel [ http://antwrp.gsfc.…]. Like all of Uranus' large moons, Oberon [ http://bang.lanl.go…] is composed of roughly half ice and half rock. Note that Oberon has at least one large mountain, visible on the limb at the lower left, that rises 6 km off the surface.
