Its orbital period is 34 hours and, like that of the Moon, is synchronous with its rotation period, which means it always shows the same face to Uranus, a condition known as tidal locking. Miranda's orbital inclination (4.34°) is unusually high for a body so close to its planet – roughly ten times that of the other major Uranian satellites ...
Semi-synchronous orbit: An orbit with an orbital period equal to half of the average rotational period of the body being orbited and in the same direction of rotation as that body. For Earth this means a period of just under 12 hours at an altitude of approximately 20,200 km (12,544.2 miles) if the orbit is circular. [16]
Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.
The only known group among Uranus's irregular moons is the Caliban group, which is clustered at orbital distances between 6–7 million km (3.7–4.3 million mi) and inclinations between 141°–144°. [14]
It is also designated Uranus VI. [10] Other than its orbit, [4] size of 50 × 36 km, [5] and geometric albedo of 0.06, [7] virtually nothing is known about it. In the Voyager 2 images, Cordelia appears as an elongated object with its major axis pointing towards Uranus. The ratio of axes of Cordelia's prolate spheroid is 0.7 ± 0.2. [5]
S/2023 U 1 has an average orbital eccentricity of 0.25 and an average inclination of 144° with respect to the ecliptic, or the plane of Earth's orbit. [3] Since S/2023 U 1's orbital inclination is greater than 90°, the moon has a retrograde orbit, meaning it orbits in the opposite direction of Uranus' orbit around the Sun. [5] Due to ...
Titania orbits Uranus at the distance of about 436,000 kilometres (271,000 mi), being the second farthest from the planet among its five major moons after Oberon. [g] Titania's orbit has a small eccentricity and is inclined very little relative to the equator of Uranus. [4] Its orbital period is around 8.7 days, coincident with its rotational ...
Puck's orbit is located between the rings of Uranus and Miranda. Little is known about Puck aside from its orbit, [4] radius of about 81 km, [5] and geometric albedo in visible light of approximately 0.11. [8]
