Uranus has 28 confirmed moons, discovered by different astronomers from 1787 to 2023. The first two moons, Titania and Oberon, were found by William Herschel in 1787, and the next two, Ariel and Umbriel, by William Lassell in 1851.

Uranus has 28 known moons, including five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon.. Oberon and Titania are the largest Uranian moons, and were the first to be discovered – by William Herschel in 1787. William Lassell, who had been the first to see a moon orbiting Neptune, discovered the next two, Ariel and Umbriel.

The planet Uranus has 27 known moons. Uranus’s five largest moons—Miranda, Ariel, Umbriel, Oberon, and Titania—range from about 240 to 800 km (150 to 500 miles) in radius. All were discovered telescopically from Earth, four of them before the 20th century. Ten small inner moons were found by Voyager 2 in 1985–86. An 11th tiny inner moon, Perdita, photographed by Voyager near the orbit ...

Before any more Uranian moons were discovered, William Lassell sometimes adopted Herschel's numbers where Titania and Oberon are respectively Uranus II and IV, [24] and sometimes called them respectively Uranus I and II. [25] After he discovered Ariel and Umbriel in 1851, Lassell numbered the four real Uranian satellites then known outward from ...

Significant Events. March 13, 1781: British astronomer William Herschel discovers Uranus – the first new planet discovered since ancient times – while searching for faint stars. 1787-1851: Four Uranian moons are discovered and named Titania, Oberon, Ariel and Umbriel. 1948: Another moon, Miranda, is discovered. March 10, 1977: While observing Uranus' passing in front of a distant star (SAO ...

Uranus - Rings, Moons, Axis: Uranus was discovered by the English astronomer William Herschel, who had undertaken a survey of all stars down to eighth magnitude—i.e., those about five times fainter than stars visible to the naked eye. On March 13, 1781, he found “a curious either nebulous star or perhaps a comet,” distinguished from the stars by its clearly visible disk.

The innermost moons are similar in characteristics with the thin rings. The five largest moons are rounded, and four of them show some kind of internal activity which shapes their surfaces. William Herschel who discovered Uranus in 1781 also observed the largest two moons, Titania and Oberon, in 1787. Notable Moons – Miranda, Titania, Ariel ...

Otherwise, numerous Uranian moons have been discovered by ground telescopes, but they mostly appear as fuzzy dots. Uranus' largest two satellites, ... Uranus' moon Miranda, with a diameter of 480 km, has among the most jumbled surfaces in the Solar System, including the tallest cliff, Verona Rupes, with a height of 20 km (12 mi). The remaining ...

The 7th planet – Uranus – was discovered on March 13, 1781, completely by accident. ... Currently Uranus has 13 known rings and 28 known moons, most of which are small.

Moons. Like other giant planets Uranus has many moons. Until now 27 satellites have been discovered, and were named after characters from the works of Shakespeare and Alexander Pope. Although the Uranian satellite system is the least massive among those of the giant planets.

Uranus has at least 27 moons known to orbit it. Its largest moons are Titania, Oberon, Umbriel, Ariel and Miranda. Titania and Oberon were discovered by William Herschel in 1787. Herschel was the astronomer who discovered Uranus itself six years earlier.

While most satellites orbiting other planets take their names from ancient mythologies, Uranus' moons are unique in being named for Shakespearean characters, along with a couple of the moons being named for characters from the works of Alexander Pope. ... William Lassell, who had been the first to see a moon orbiting Neptune, discovered the ...

William Lassell, who was also the first to see a moon orbiting Neptune, discovered Uranus' next two moons, Ariel and Umbriel. Nearly a century passed before Dutch-American astronomer Gerard Kuiper ...

Herschel noticed that one of these "stars" seemed different, and after observing it many more times, noticed that it orbited the Sun. He calculated that Uranus had an orbit that was about 18 times farther from the Sun than Earth. Herschel also discovered two of the moons of Uranus (Titania and Oberon).

Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round satellites.It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda from William Shakespeare's play The Tempest. [9] Like the other large moons of Uranus, Miranda orbits close to its planet's equatorial plane.. Because Uranus orbits the Sun on its side ...

It features his discoveries, including Mimas and Enceladus (circling Saturn), and two moons of Uranus: Titania and Oberon. The museum is open to visitors and tours. There is a renaissance of interest in William Herschel's music, and a recording of his most popular works is available.

Nasa’s Voyager 2 was the first, and so far the only, visitor to Uranus. Voyager 2 flew within 50,600¹ miles of Uranus’s outermost clouds and discovered 10 new moons and two new rings. Voyager also discovered that Uranus’s magnetic field is stronger than that of Saturn.

Miranda, innermost and smallest of the five major moons of Uranus and, topographically, the most varied of the group. It was discovered in telescopic photographs of the Uranian system in 1948 by the Dutch American astronomer Gerard P. Kuiper, who named it after a character in William Shakespeare’s play The Tempest.. Miranda revolves around Uranus once every 1.413 days in a nearly circular ...
