Oberon, Moon of Uranus

Oberon is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 3,666,236.83 km. The furthest it gets from its orbital parent (apoasis) is 584,317 km. Its mass is estimated/calculated at being 2,883,438,065,279,000,000,000 kg. Its density has been calculated at being 1.559 g/cm3. Its volume is 1.559 g/cm3. It was discovered in the year 1787 by W. Herschel.

The Semi-Major Axis of the orbit is 583,500 km, which is the furthest point from the centre to the edge of an elliptical point.

The mass of the object is calculated at being 2,883,438,065,279,000,000,000 kg. The equatorial circumference of Oberon is 4,784.0 km. The mean radius of Oberon is 761.4 km. The surface area of Oberon is 7,285,101.53 km2. The surface gravity of the said item is 0.332 m/s2. The average orbit velocity, that is the speed at which it orbits is 11,349.2 km/h.

The orbital inclination, the angle at which Oberon orbits in relation to the orbital plane is 0.068 degrees. The orbital eccentricity is 0.0014, it is the degree at which Oberon orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Discovery of Oberon and Naming

The moon Oberon was discovered by Sir William Herschel, the famous German born British Astronomer. Sir William is famous for discovering not just the moon but also the planet it orbits. At a time when astronomy was really taking off, the International Astronomical Union wasn't around so there was carte blanche to name objects. The moons were named by John Herschel, Williams son. Planets Edu.

Nowadays, you can't just name planets any way you like. Moon names have to be officially recognised by the I.A.U. All Uranus moons after named after characters from William Shakespeare or from other literally greats such as Alexander Pope's 'Rape of the Lock'. Rape is in non-criminal sense, that is to grab, take, snatch.

Craters, Canyons and Surface of Oberon

Of the moons of Uranus, Oberon is the second largest. Oberon is the moon furthest out from the planet and is heavily cratered and has a large number of canyons, goes with being slightly unshielded by other moons. It is made up of rock and water ice. The only time it has been visited is by the Voyager 2 space probe. The largest crater on the moon is named Hamlet and is 206 kilometres in diameter. The largest canyon is Mommur Chasma, named after the enchanted forest in the Midsummers play, Ref: PlanetEdu

Some of the craters are filled with an unknown liquid which astronomer speculate as being dirty water, having come from inside. The planet has been geologically stable in the main but there is one mountain that is four miles high. SeaSky

Oberon Legend Mythology

The name Oberon is not from Ancient Greek or Roman lore that so many objects in space are named after. Oberon comes from William Shakespeare's tale 'A Midsummer's Night Tale'. Oberon is the king of the fairies. Titania, another moon that orbits Uranus. Oberon is the master of the servant Puck.

Oberon in the play is a bit of ladies man who goes wandering. He's can be both caring and uncaring, he'll wish good luck on a family so that they won't have ugly kids. Oberon and Titania are rowing in the play which has a negative effect on the weather. The weather then affects the crops which affects the humans. The moons are too far away to have any effect on the weather on our planet. Shmoop
