The five main satellites are Miranda, Ariel, Umbriel, Titania, and Oberon.

Titania's accretion probably lasted for several thousand years.

Titania has a relatively low Bond albedo of about 17 .

The cracking of the crust was caused by the global expansion of Titania by about 0.7 .

The name Titania was taken from the Queen of the Fairies in A Midsummer Night's Dream .

Titania may be differentiated into a rocky core surrounded by an icy mantle.

The pressure in the center of Titania is about 0.58 GPa (5.8 kbar).

Ariel is believed to have once been held in a 4 1 resonance with Titania.

Another possible source is the outgassing of the primordial CO2 trapped by water ice in Titania's interior.

Scientists have recognized three classes of geological feature on Titania craters, chasmata (canyons) and rupes (scarps).

Titania's surface is intersected by a system of enormous faults, or scarps.

In other words, Titania is a synchronous or tidally locked satellite, with one face always pointing toward the planet.

The grabens on Titania are wide and have a relief of about 2 5 km.

Titania was initially referred to as the first satellite of Uranus , and in 1848 was given the designation by William Lassell, although he sometimes used William Herschel's numbering (where Titania and Oberon are II and IV).

It took several images of Titania, which allowed mapping of about 40 of the moon s surface.

The geology of Titania was influenced by two competing forces impact crater formation and endogenic resurfacing.

The largest of Uranus's satellites, Titania, has a radius of only 788.9 km, 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.

These smooth plains were probably resurfaced later in Titania's geological history, after the majority of craters formed.

Titania is the largest of the moons of Uranus and the eighth largest moon in the Solar System at a diameter of .

The surface of Titania, which is relatively dark and slightly red in color, appears to have been shaped by both impacts and endogenic processes.

Titania is thought to have lost a significant amount of carbon dioxide since its formation 4.6 billion years ago.

Orbit Titania orbits Uranus at the distance of about , being the second farthest from the planet among its five major moons.

Composition and internal structure Titania is the largest and most massive Uranian moon, and the eighth most massive moon in the Solar System.

Titania consists of approximately equal amounts of ice and rock, and is probably differentiated into a rocky core and an icy mantle.

The surface of Titania is less heavily cratered than the surfaces of either Oberon or Umbriel, which means that it is much younger.

Surface features Among Uranus's moons, Titania is intermediate in brightness between the dark Oberon and Umbriel and the bright Ariel and Miranda.

The most prominent among Titania's canyons is Messina Chasma, which runs for about from the equator almost to the south pole.

With a large telescope of 25 cm or wider, cloud patterns, as well as some of the larger satellites, such as Titania and Oberon, may be visible.

In 2007 2008 a number of such events were observed including two occultations of Titania by Umbriel on August 15 and December 8, 2007.

Atmosphere The presence of carbon dioxide on the surface suggests that Titania may have a tenuous seasonal atmosphere of CO2, much like that of the Jovian moon Callisto.

Like all major moons of Uranus, Titania probably formed from an accretion disk which surrounded the planet just after its formation.

In 1851 Lassell eventually numbered all four known satellites in order of their distance from the planet by Roman numerals, and since then Titania has been designated .

Except for water, the only other compound identified on the surface of Titania by infrared spectroscopy is carbon dioxide, which is concentrated mainly on the trailing hemisphere.

Exploration So far the only close up images of Titania have been from the Voyager 2 probe, which photographed the moon during its flyby of Uranus in January 1986.

Discovery and naming Titania was discovered by William Herschel on January 11, 1787, the same day he discovered Uranus's second largest moon, Oberon.

At the maximum temperature attainable during Titania's summer solstice (89 K), the vapor pressure of carbon dioxide is about 3 nbar.

After the end of formation, the subsurface layer cooled, while the interior of Titania heated due to decay of radioactive elements present in its rocks.

At the time of the flyby, the southern hemisphere of Titania (like those of the other moons) was pointed towards the Sun, so the northern (dark) hemisphere could not be studied.

He writes that the fairies make light of love by mistaking the lovers and by applying a love potion to Titania's eyes, forcing her to fall in love with an ass.

However, the color asymmetry of Titania is more likely related to accretion of a reddish material coming from outer parts of the Uranian system, possibly, from irregular satellites, which would be deposited predominately on the leading hemisphere.

The precise composition of the subnebula is not known however, the relatively high density of Titania and other Uranian moons compared to the moons of Saturn indicates that it may have been relatively water poor.

On September 8, 2001, Titania occulted a bright star (HIP106829) with a visible magnitude of 7.2 this was an opportunity to both refine the moon's diameter and ephemeris, and to detect any extant atmosphere.

Since the closest distance between Voyager 2 and Titania was only , the best images of this moon have a spatial resolution of about 3.4 km (only Miranda and Ariel were imaged with a better resolution).

Since the vapor pressure of CO2 is a steep function of temperature, this may lead to the accumulation of carbon dioxide in the low latitude regions of Titania, where it can stably exist on high albedo patches and shaded regions of the surface in the form of ice.

It is the brawl between Oberon and Titania, based on a lack of recognition for the other in the relationship, that drives the rest of the drama in the story and makes it dangerous for any of the other lovers to come together due to the disturbance of Nature caused by a fairy dispute.
