Oberon is a natural satellite of Uranus. It is one of the five satellites discovered prior to the Voyager 2 encounter of January 1986. It is named after a character from William Shakespeare's A Midsummer Night's Dream.
Oberon has a radius of 761.4km. Its surface gravity is 0.346m/s^2, 0.035 that of Earth. A Surface Orbit has a speed of 514m/s, and the Escape Velocity is 727m/s. A surface orbit has a period of 9309s (about 2 hours 35 minutes).
Like all the satellites of Uranus, Oberon's axis is tilted 98° relative to the ecliptic plane. It is locked in synchronous rotation, like the Earth's moon. When Voyager flew past, Uranus and all its satellites were near their southern summer solstice, and in this case it means that only the southern hemispheres were visible. As a consequence, only the southern hemisphere of Oberon has been mapped in any detail.
Oberon is a satellite included in the Orbiter base installation. It has no bases on its surface.
