''[[w:Oberon (moon)|Oberon]]'' is the second largest and second most massive [[natural satellite]] of [[Uranus]]. It was discovered on 11 January 1787 by [[w:William Herschel|William Herschel]], and was named after a character from William Shakespeare's ''[[w:A Midsummer Night's Dream|A Midsummer Night's Dream]]''. It is one of the five satellites of Uranus discovered prior to the Voyager 2 encounter of January 1986. 

Oberon has a radius of 761.4km. Its surface gravity is 0.349m/s^2, 0.036 that of Earth. A [[Surface Orbit|surface orbit]] has a speed of 515m/s, and the [[Escape Velocity|escape velocity]] is 729m/s. A surface orbit has a [[Orbital Period|period]] of 9283s (about 2 hours 35 minutes).

Oberon's orbit about Uranus is almost perfectly circular and equatorial, and has a radius of 583400km. Its orbital period is 13.463 days. This is the outermost of the five major satellites.

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 has a mean density of about 1.6 times that of water. From this, we can conclude that the satellite is mostly water ice, with a little bit of rock mixed in.
