January 11, 1787 Slough W. Herschel Uranus V (Miranda) Named by Kuiper for the heroine of Shakespeare's "The … Oberon orbits Uranus at the distance of about 584,000 km, being the farthest from the planet among its five major moons. 125-129, 1787; and "On George's Planet and its satellites", Philosophical Transactions of the Royal Society of London, Vol. [26] The eutectic temperature of this mixture is 176 K.[26] If the temperature dropped below this value the ocean would have frozen by now. Oberon spends a significant part of its orbit outside the Uranian magnetosphere. One more satellite, discovered in 2003, is yet to be named. Oberon has a low Bond albedo of about 14%. [28], Oberon is thought to have formed from an accretion disc or subnebula: a disc of gas and dust that either existed around Uranus for some time after its formation or was created by the giant impact that most likely gave Uranus its large obliquity. [32] Many large craters are surrounded by bright impact ejecta (rays) consisting of relatively fresh ice. Discovered by William Herschel in 1787, Oberon is named after the mythical king of the fairies who appears as a character in Shakespeare's A Midsummer Night's Dream. It was the first step in creating a wider system of UK-owned satellites. Astronomy Domine, a song by Pink Floyd, refers to Titania as well as Oberon and Miranda. [4] Its orbital period is around 13.5 days, coincident with its rotational period. Oberon was discovered on January 11, 1787 by William Herschel. Who is the longest reigning WWE Champion of all time? The only satellite of Uranus to have more craters is Oberon, and the planet is believed to be geologically stable. Since the closest approach of Voyager 2 to Oberon was 470,600 km,[41] the best images of this moon have spatial resolution of about 6 km. Copyright © 2020 Multiply Media, LLC. The astronmer William Lassell, who discovered two of Uranus' satellites in 1851, started the tradition of naming all of the planet's satellites for characters in the work of William Shakepseare and Alexander Pope. Oberon, juga disebut Uranus IV, adalah satelit alami terluar planet Uranus. It was is discovered by William Herschel in 1787; Oberon … If the ice contains enough ammonia or other antifreeze, Oberon may possess a liquid ocean layer at the core–mantle boundary. Titania (/ t ɪ ˈ t ɑː n i ə /), also designated Uranus III, is the largest of the moons of Uranus and the eighth largest moon in the Solar System at a diameter of 1,578 kilometres (981 mi). A layer of liquid water ('ocean') rich in dissolved ammonia may have formed at the core–mantle boundary. [8] The canyons' sides are probably scarps produced by normal faults[g] which can be either old or fresh: the latter transect the bright deposits of some large craters, indicating that they formed later. In other words, Oberon is a synchronous satellite, tidally locked, with one face always pointing toward the planet. [16] The names of all four satellites of Uranus then known were suggested by Herschel's son John in 1852, at the request of William Lassell,[17] who had discovered the other two moons, Ariel and Umbriel, the year before. D. Moon. The nature of the dark patches, which mainly occur on the leading hemisphere and inside craters, is not known. Oberon is a satellite of which planet? It is covered by numerous impact craters reaching 210 km in diameter. Moon - a rugged wilderness of mountains, valleys and gorges, illuminated now by the ghostly green radiance of the huge planet that hung in the heavens overhead, and also by the ominous red flare of countless volcano craters that seethed and … A) Mercury B) Neptune C) Uranus D) Mars: In 1912, former US president Theodore Roosevelt was a candidiate for which political party? Discovered in 1787, little was known about this moon until Voyager 2 passed it during its flyby of Uranus in January 1986. This is the opposite of what is observed on other Uranian moons, where the leading hemisphere exhibits stronger water ice signatures. Who are the famous writers in region 9 Philippines? Oberon orbits Uranus at a distance of about 584,000 km, being the farthest from the planet among its five major moons.Template:Efn Oberon's orbit has a small orbital eccentricity and inclination relative to the equator of Uranus. A) Naval … How old was queen elizabeth 2 when she became queen? B. Rhea. 77, pp. But in the literature of the Old Solar System it is a hot, lonely, desolate place. Oberon (ō`bərŏn'), in astronomy, one of the moons, or natural satellites, of Uranus Uranus, in astronomy, 7th planet from the sun, at a mean distance of 1.78 billion mi (2.87 billion km), with an orbit lying between those of Saturn and Neptune; its period of revolution is slightly more than 84 years. The surface of Oberon, which is dark and slightly red in color, appears to have been primarily shaped by asteroid and comet impacts. He would later report four more satellites, which would turn out to be spurious. Oberon orbitează Uranus la o distanță de aproximativ 584.000 km, fiind cel mai îndepărtat de planetă dintre cei cinci mari sateliți. The Solar System's planets, and its most likely dwarf planets, are known to be orbited by at least 218 natural satellites, or moons. Oberon's orbit. [31] Still, present knowledge of the evolution of Oberon is very limited. The eight moons more massive than Oberon are. [31] The images cover about 40% of the surface, but only 25% of the surface was imaged with a resolution that allows geological mapping. [33] Oberon's surface is intersected by a system of canyons, which, however, are less widespread than those found on Titania. [34] The canyons obliterated parts of the older surface. [8] The presence of water ice is supported by spectroscopic observations, which have revealed crystalline water ice on the surface of the moon. [10] The Voyager 2 flyby coincided with the southern hemisphere's 1986 summer solstice, when nearly the entire northern hemisphere was in darkness. In other words, Oberon is a synchronous satellite, tidally locked, with one face always pointing toward the planet. It is also the most riddled with impact craters out of Uranus's satellites and moons next to Oberon. More Moons: Before the 1986 Voyager encounter, Uranus was known to have five moons. [9] Its surface shows a strong opposition surge: its reflectivity decreases from 31% at a phase angle of 0° (geometrical albedo) to 22% at an angle of about 1°. Oberon was discovered on January 11, 1787, by astronomer William Herschel. [10] The cause of this asymmetry is not known, but it may be related to impact gardening (the creation of soil via impacts) of the surface, which is stronger on the leading hemisphere. [ + link to: What to see on Oberon] The outermost satellite of far Uranus, Oberon must be a cold, lonely, desolate place.

Oberon's orbit has a small orbital eccentricity and inclination relative to the equator of Uranus. [23] This bombardment may lead to the darkening of the trailing hemispheres, which is actually observed for all Uranian moons except Oberon (see below). [26] The current state of the icy mantle is unclear. [34] The former acted over the moon's entire history and is primarily responsible for its present-day appearance. Satelit ini merupakan satelit terbesar kedua Uranus sekaligus satelit terbesar kesembilan di Tata Surya. [11], All of the moons of Uranus are named after characters created by William Shakespeare or Alexander Pope. But in the literature of the Old Solar System it is a hot, lonely, desolate place.. Stid: Hot or cold, I'm surprised it's catered for at all. Find the gravitational … [39] The maximum temperature of around 230 K was reached at the depth of about 60 km. [note 2] Oberon's orbit has a small orbital eccentricity and inclination (relative to the equator of Uranus). Oberon [O-buh-ron] is a moon of Uranus that is characterized by an old, heavily cratered, and icy surface. Explanation: Oberon is the natural satellite of the planet Uranus. Oberon is the outermost of the major moons of the planet Uranus. Outermost satellite of Uranus, discovered by Herschel in 1787. «Oberon» is the outermost of the main physical satellites of the planet Uranus. 7. URANUS. [10] The dark material itself may have formed as a result of radiation processing of methane clathrates or radiation darkening of other organic compounds.[8][27]. [29], Scientists have recognized two classes of geological feature on Oberon: craters and chasmata ('canyons'—deep, elongated, steep-sided depressions[30] which would probably be described as rift valleys or escarpments if on Earth).
