Titania

Uranus’s largest moon

Voyager 2 images show Titania’s impact craters and long faults. Its large canyon systems record extension of the icy crust.

Mean diameter: 1,577.8 km
Mean orbital distance: 436,298 km from centre
Orbital period: 8.706 Earth days

One diameter scale. Circle shapes compare volume-equivalent diameters; irregular moons are not spheres.

Orbit & discovery

Surface gravity: 0.365 m/s²
Discovery: 1787
Discoverer / team: W. Herschel
Provisional designation: —
JPL satellite ID: 703
Orbital eccentricity: 0.002
Inclination: 0.1 degrees

Inclination reference: equatorial. Mean-element epoch: 2000-01-01.5 TDB · URA182.

Diameters use volume-equivalent mean radii, including for irregular bodies. Mean orbital elements describe an orbit; they are not live positions. Missing physical measurements remain unavailable.
