What is the Largest Moon of Uranus?

The question “what is the largest moon of Uranus?” often conjures up images of Miranda, Umbriel, Titania, or Oberon. However, there are many other names for this large planet. Here are a few facts about these moons. They are all rocky and may be interesting to learn more about. Here are a few facts about each moon. Hopefully, you’ll find this information interesting and useful.


Miranda is one of the largest moons in the Solar System, but it appears nearly invisible to amateur astronomers. The largest spacecraft flyby of Miranda occurred in 1986, and all of the information about Miranda was obtained during that mission. The southern hemisphere of Miranda was facing the Sun during the flyby, while the northern hemisphere was in darkness. No future missions to Miranda have been planned, although a mission would be worthwhile if more knowledge could be gained about its history.

The large, irregular surface of Miranda is unique, containing huge fault canyons. These canyons may be as deep as 20 kilometers. The surfaces of Miranda are layered and terraced, showing the juxtaposition of old and young materials. The terrain suggests that Miranda was likely damaged by massive meteorite impacts during its evolution. The result would have been episodic periods of slushy water rising to the surface.

Miranda is the innermost large moon of Uranus, and the smallest and oddest of the four. It orbits close to Uranus, and it follows a perpendicular path to the ecliptic. The unusual orbit of Miranda may result from close encounters with other Uranian moons. The moon has a rocky core, which is likely the source of its bright surface.

Miranda was first discovered in 1948 at the McDonald Observatory in Texas. It was the last of Uranus’ moons discovered until the Voyager 2 spacecraft visited the planet in 1986. The astronomers who discovered Miranda attributed its name to Miranda, a character from the Shakespeare play The Tempest. Miranda’s orbit is almost perpendicular to the ecliptic, and it shares the same extreme seasonal cycle as Uranus.


Umbriel is the third largest moon of Uranus. It is composed of approximately equal amounts of rock and water ice. Voyager 2 images of Umbriel show that its surface is remarkably stable since the Late Heavy Bombardment. Dark polygons resembling canyons are present on the moon’s surface. They range in size from tens of kilometers to hundreds of kilometers across. Voyager 2 images also reveal that these dark patches trend in a northeast to southwest direction. Because Uranus orbits the sun on its side, the planet experiences a highly extreme seasonal cycle and has two poles.

Umbriel is one of the darkest and largest moons in the Solar System. Voyager 2 imaged 35 percent of its surface. The moons Ariel and Titania are among the largest in the Solar System, and are both cratered. The rocky surface of Umbriel is the darkest of any of the Uranian moons. Although Titania is the eighth largest in the Solar System, it is not as dark as Umbriel.

Miranda is the innermost of Uranus’ five major satellites. It has giant fault canyons that are at least 12 times deeper than the Grand Canyon. The surface of Miranda is also extremely dark, but it can also appear much younger than it actually is. Ariel is the largest of the five major satellites, and it sports a mysterious bright ring on its side. Oberon is the most distant satellite and shows little internal activity. Many of its craters contain unidentified dark material. The other two moons are Ophelia and Cordelia, shepherd moons.

It is important to understand the differences between the four moons. Umbriel and Miranda have slightly different orbital periods. They are similar in size and mass, but they do not have the same magnetic fields. The four moons of Uranus have different orbital periods. It is also possible to see different features on each of them. It is possible to observe their magnetic fields with a telescope and determine how far they are from the Sun.


Scientists have hypothesized that Titania has a rocky core and a liquid ocean beneath its icy surface. However, it does not meet the other criteria for life. In addition to being the largest moon of Uranus, it is also the densest. There is a significant amount of rocky material in Titania’s interior, which is thought to make up about two-thirds of the moon’s total radius. The moon is not completely ice-free, and its internal heating mechanism is unknown. Titania may have an ocean, but this is only a speculative hypothesis that could have been formed from Uranus’s debris. If so, it could have formed during a collision with Uranus.

The planet Uranus has a tilted equatorial plane, which results in a nearly circular orbit around the Sun. Because of its tilt, its moons experience 42-year cycles of total darkness. Scientists think Titania is made up of nearly equal parts of ice and rock. Scientists have also detected crystalline water ice on Titania’s surface.

Scientists are able to study Titania’s surface through high-powered telescopes to discover more about the planet and its moons. In 1986, Voyager 2 made flybys of Titania. But it was unable to photograph the entire surface of Titania. Despite its apparent lack of brightness, the images provided a better picture of the moon’s surface. Some craters are so large that they can be measured in miles.

In addition to being the most distant major satellite of Uranus, Titania has a tidally-locked orbit, making it nearly impossible for it to make contact with the planet. Its orbit is 436,000 kilometers across, making it the second-farthest of all five major Uranian moons. It completes a rotation of the planet every 8.7 days. It is thought to have water ice and a thin atmosphere of carbon dioxide.


While a moon’s size is generally considered small, the size of a planet’s largest one is very large. As Uranus has no rings, the moons are believed to be rocky. Several of the moons of Uranus have been named for famous literary characters, most notably William Shakespeare and Alexander Pope. Oberon is named after the king of the fairies in Shakespeare’s play A Midsummer Night’s Dream. The moon’s mass is 3.014 x 1021 kilograms, making it the ninth most massive moon in the solar system.

Until recently, only one of the 27 natural satellites of Uranus has been studied up close. In 1986, Voyager 2 captured images of Oberon. These images showed 40% of the surface of the planet, but were not good enough to map its geology. This limited the mission’s ability to study the northern hemisphere. However, scientists are now working to understand the origin of these strange features.

While other Uranian moons are unremarkable, Oberon is an exception. Its surface is cratered heavily. Three of the moon’s four craters are named after male characters from Shakespeare, including Hamlet and Macbeth. The largest crater, known as the Hammur Chasma, is 537 kilometers across. Located in the equatorial region of the planet, this feature has a rough circular shape and is part of Uranus’ magnetic field.

The largest of the four moons of Uranus is Titania, which was discovered by William Herschel in 1787. Herschel named the first four moons after famous literary characters, including William Shakespeare and Alexander Pope. However, this hasn’t stopped people from calling their satellites by their literary names. It is possible that there are many other moons orbiting the giant planet, but it is difficult to pinpoint the exact names.


Despite its relatively small size, the largest moon of Uranus is named after a fictional character in Shakespeare’s play, “A Midsummer Night’s Dream”. This mischievous sprite wanders the world at night, accompanied by fairies, and many believe he has the powers of an evil demon. Puck is designated Uranus XV. There are no other moons named after ancient deities.

Uranus’ moons are classified into three groups: the five major and irregular. The five major moons are small dark bodies and have a similar composition to Uranus’s rings. The irregular moons have elliptical and highly inclined orbits, and have great distances from the planet. Although they are small, their characteristics make them interesting to study. In addition to these, Uranus’ moons are often visited by spacecraft.

Voyager 2 and the New Horizons spacecraft have both spotted three of Uranus’ inner moons. The outermost moon, Miranda, has nine satellites, but only two have been studied. In 2003, two more inner moons were discovered. The orbit of the inner moons of Uranus is unstable, which means that each of them is prone to encounter other planets and craters.

The inner moon of Uranus, Puck, was discovered by Voyager 2 in December 1985 and named after a character from Shakespeare. Puck has a low albedo and is in the orbit between Miranda and the rings of Uranus. Puck’s surface is heavily cratered and has spectral signs of water ice. Therefore, Puck is the sixth largest moon of Uranus.
