Discovery

Titania was discovered on January 11, 1787 by William Herschel. He reported it and Oberon the same year.^[1] He later reported four more satellites, which turned out to be spurious.^[2] is the 11th day of the year in the Gregorian calendar. ...

Name and pronunciation

This Voyager 2 image of Titania shows enormous rifts.

The names of Titania and the other four satellites of Uranus then known were suggested by Herschel's son John Herschel in 1852 at the request of William Lassell, who had discovered Ariel and Umbriel the year before.^[3] Lassell had earlier endorsed Herschel's 1847 naming scheme for the seven then-known satellites of Saturn and had named his newly-discovered eighth satellite Hyperion in accordance with Herschel's naming scheme in 1848. Trajectory Voyager 2 is an unmanned interplanetary spacecraft, launched on August 20, 1977. ... John Herschel Sir John Frederick William Herschel (7 March 1792 – 11 May 1871) was an English mathematician and astronomer. ... William Lassell (June 18, 1799 – October 5, 1880) was a British astronomer, born in Bolton, Lancashire, England. ... Atmospheric pressure 0 kPa Ariel (air-ee-əl, IPA ) is a moon of Uranus discovered on 24 October 1851 by William Lassell. ... Atmospheric pressure 0 kPa Umbriel (um-bree-əl, IPA ) is a moon of Uranus discovered on 1851-10-24 by William Lassell. ... Hyperion (IPA: , Greek Ὑπερίων) is a moon of Saturn discovered by William Cranch Bond, George Phillips Bond and William Lassell in 1848. ...

All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Titania was named after Titania, the Queen of the Faeries in A Midsummer Night's Dream. Wikipedia does not yet have an article with this exact name. ... For other uses, see Alexander Pope (disambiguation). ...

Shakespeare's character's name is pronounced /tɨˈtɑːnjə/, but the moon is often /taɪˈteɪniə/, by analogy with the familiar chemical element titanium.

It is also designated Uranus III.

Physical characteristics

The rift Messin Chasma is highlighted in this view of Titania's crescent phase (apparently a reprojection of the image above).

So far the only close-up images of Titania are from the Voyager 2 probe, which photographed the moon during its Uranus flyby in January, 1986. At the time of the flyby the southern hemisphere of the moon was pointed towards the Sun so only it was studied. Trajectory Voyager 2 is an unmanned interplanetary spacecraft, launched on August 20, 1977. ... Sol redirects here. ...

Although its interior composition is uncertain, one model suggests that Titania is composed of roughly 50% water ice, 30% silicate rock, and 20% methane-related organic compounds. A major surface feature is a huge canyon that dwarfs the scale of the Grand Canyon on Earth and is in the same class as the Valles Marineris on Mars or Ithaca Chasma on Saturn's moon Tethys. In chemistry, a silicate is a compound containing an anion in which one or more central silicon atoms are surrounded by electronegative ligands. ...

• Craters
• Rupes (scarps)

It is used in planetary geology to refer to escarpments on other planets and moons. ... In geology, an escarpment is a transition zone between different physiogeographic provinces that involves an elevation differential, often involving high cliffs. ...

Occultation

On September 8, 2001, Titania occulted a faint star; this was an opportunity to both refine its diameter and ephemeris, and to detect any extant atmosphere. The data revealed no atmosphere to a surface pressure of 0.03 microbars; if it exists, it would have to be far thinner than that of Triton or Pluto.^[4][5] is the 251st day of the year (252nd in leap years) in the Gregorian calendar. ... Year 2001 (MMI) was a common year starting on Monday (link displays the 2001 Gregorian calendar). ... In this July, 1997 still frame captured from video, the bright star Aldebaran has just reappeared on the dark limb of the waning crescent moon in this predawn occultation. ... An ephemeris (plural: ephemerides) (from the Greek word ephemeros = daily) is a device giving the positions of astronomical objects in the sky. ... Triton (trye-tÉ™n, IPA: , Greek Τρίτων), or Neptune I, is the planet Neptunes largest moon. ... For other uses, see Pluto (disambiguation). ...
