Ariel is a satellite of which planet?
"Ariel (moon) Ariel is the fourth-largest of the 27 known moons of Uranus. Ariel orbits and rotates in the equatorial plane of Uranus, which is almost perpendicular to the orbit of Uranus and so has an extreme seasonal cycle. It was discovered in October 1851 by William Lassell and named for a character in two different pieces of literature. As of 2017, much of the detailed knowledge of Ariel derives from a single flyby of Uranus performed by the spacecraft ""Voyager 2"" in 1986, which managed to image around 35% of the moon's surface. There are no active plans at"
"Ariel 2 Ariel 2, also known as UK-C, was a British radio astronomy satellite, which was operated by the Science and Engineering Research Council as part of the Ariel programme. It was built in America by Westinghouse Electric, and had a mass at launch of . It was launched in 1964, and became the first satellite to be used for radio astronomy. The launch of Ariel 2 was conducted by the United States National Aeronautics and Space Administration, using a Scout X-3 rocket. The launch occurred at 17:25:23 GMT on 27 March 1964, from Launch Area 3 at the Wallops"
"Ariel 1 Ariel 1 (also known as UK-1 and S-55), was the first British satellite, and the first satellite in the Ariel programme. Its launch in 1962 made the United Kingdom the third country to operate a satellite, after the Soviet Union and the United States. It was constructed in both the UK and the United States by NASA Goddard Space Flight Center and SERC, under an agreement reached as the result of political discussions in 1959 and 1960. In late 1959, the Science and Engineering Research Council proposed the development of Ariel 1 to NASA, following an offer made"

"largest of Uranus's satellites, Titania, has a radius of only , or less than half that of the Moon, but slightly more than Rhea, the second-largest satellite of Saturn, making Titania the eighth-largest moon in the Solar System. Uranus's satellites have relatively low albedos; ranging from 0.20 for Umbriel to 0.35 for Ariel (in green light). They are ice–rock conglomerates composed of roughly 50% ice and 50% rock. The ice may include ammonia and carbon dioxide. Among the Uranian satellites, Ariel appears to have the youngest surface with the fewest impact craters and Umbriel's the oldest. Miranda has fault canyons"
"another Uranian satellite, Ariel, was discovered by William Lassell on October 24, 1851. Although William Herschel, the discoverer of Titania and Oberon, claimed at the end of the 18th century that he had observed four additional moons of Uranus, his observations were not confirmed and those four objects are now thought to be spurious. All of Uranus's moons are named after characters created by William Shakespeare or Alexander Pope. The names of all four satellites of Uranus then known were suggested by John Herschel in 1852 at the request of Lassell. Umbriel is the ""dusky melancholy sprite"" in Alexander Pope's"

"A number of such events occurred in 2007–2008, including an occultation of Ariel by Umbriel on 19 August 2007. Currently Ariel is not involved in any orbital resonance with other Uranian satellites. In the past, however, it may have been in a 5:3 resonance with Miranda, which could have been partially responsible for the heating of that moon (although the maximum heating attributable to a former 1:3 resonance of Umbriel with Miranda was likely about three times greater). Ariel may have once been locked in the 4:1 resonance with Titania, from which it later escaped. Escape from a mean motion"

"Umbriel on August 15 and December 8, 2007 as well as of Ariel by Umbriel on August 19, 2007. Currently Umbriel is not involved in any orbital resonance with other Uranian satellites. Early in its history, however, it may have been in a 1:3 resonance with Miranda. This would have increased Miranda's orbital eccentricity, contributing to the internal heating and geological activity of that moon, while Umbriel's orbit would have been less affected. Due to Uranus's lower oblateness and smaller size relative to its satellites, its moons can escape more easily from a mean motion resonance than those of Jupiter"
"the plasma's co-rotation). The energetic particles tend to sputter water ice, decompose methane trapped in ice as clathrate hydrate and darken other organics, leaving a dark, carbon-rich residue behind. Except for water, the only other compound identified on the surface of Ariel by infrared spectroscopy is carbon dioxide (CO), which is concentrated mainly on its trailing hemisphere. Ariel shows the strongest spectroscopic evidence for CO of any Uranian satellite, and was the first Uranian satellite on which this compound was discovered. The origin of the carbon dioxide is not completely clear. It might be produced locally from carbonates or organic"

The surface of Ariel is generally neutral in color. There may be an asymmetry between the leading and trailing hemispheres; the latter appears to be redder than the former by 2%. Ariel's surface generally does not demonstrate any correlation between albedo and geology on the one hand and color on the other hand. For instance, canyons have the same color as the cratered terrain. However, bright"

Ariel has a complex surface consisting of extensive cratered terrain cross-cut by a system of scarps, canyons, and ridges. The surface shows signs of more recent geological activity than other Uranian moons, most likely due to tidal heating. Discovered on 24 October 1851 by William Lassell, it is named for a sky spirit in Alexander Pope's ""The Rape of the Lock"" and Shakespeare's ""The Tempest"". Both Ariel and the slightly larger Uranian satellite Umbriel were discovered"
"Interference from radar signals prevented the satellite from pointing correctly, and affected the data that it returned. A Scout D-1 carrier rocket, serial number S198C, was used to launch Ariel 6 from Launch Area 3A at the Wallops Flight Center. The launch was successfully conducted at 23:26:00 UTC on 2 June 1979. The satellite was placed into a low Earth orbit, and received the International Designator 1979-047A.

Ariel 3 was also fitted with a series of mirrors to allow easy observation of the satellite. On 24 October 1967 the tape recorder aboard Ariel 3 began to malfunction. This restricted observation to real-time operation only. Ariel 3 suffered from a significant power failure in December 1968, restricting the satellite's operation to daylight hours only. The satellite was completely shut down in September 1969. Its orbit decayed steadily until on 14 December 1970 when"
"Aurora (fictional planet) Aurora is a fictional planet in Isaac Asimov's ""Robot"" series. It was the first world settled by the Spacers, originally named 'New Earth'; it was located 3.7 parsecs (12 light years) from Earth. In Asimov's fictional universe, the innermost planet orbiting Tau Ceti was mankind's very first extrasolar planetary settlement, established in 2065. Originally named ""New Earth"", in later millennia the planet would be renamed ""Aurora"", which means ""dawn"", to signify the dawning of a new age for the Spacer culture. It was also considered the strongest of the Spacer worlds, and was their ""de facto"" leader."

Their surfaces are heavily cratered, though all of them (except Umbriel) show signs of endogenic resurfacing in the form of lineaments (canyons) and, in the case of Miranda, ovoid race-track like structures called coronae. Extensional processes associated with upwelling diapirs are likely responsible for the origin of the coronae. Ariel appears to have the youngest surface with the fewest impact craters, while Umbriel's appears oldest.
