Of Uranus's five round satellites, Miranda orbits closest to it, at roughly 129 000 km from the surface; about a quarter again as far as its most distant ring. It is the rounded moon that has the smallest orbit around a major planet.
The orbits of the regular moons are nearly coplanar with Uranus's equator, which is tilted 97.77° to its orbit. Uranus's irregular moons have elliptical and strongly inclined (mostly retrograde) orbits at large distances from the planet.
Titania (/ t ə ˈ t ɑː n i ə, t ə ˈ t eɪ n i ə /), also designated Uranus III, is the largest moon of Uranus.At a diameter of 1,578 kilometres (981 mi) it is the eighth largest moon in the Solar System, with a surface area comparable to that of Australia.
Ariel is the fourth-largest moon of Uranus. Ariel orbits and rotates in the equatorial plane of Uranus, which is almost perpendicular to the orbit of Uranus, so the moon has an extreme seasonal cycle. It was discovered on 24 October 1851 [11] by William Lassell and named for a character in two different pieces of literature.
The bright S/2002 N5 moon is 14 miles (23 kilometers) in diameter and takes nearly nine years to complete an orbit of Neptune, while faint S/2021 N1 is about 8.7 miles (14 kilometers) across and ...
Its orbit lies partially outside Uranus's magnetosphere. Oberon likely formed from the accretion disk that surrounded Uranus just after the planet's formation. The moon consists of approximately equal amounts of ice and rock, and is probably differentiated into a rocky core and an icy mantle. A layer of liquid water may be present at the ...
Puck is the sixth-largest moon of Uranus. It was discovered in December 1985 by the Voyager 2 spacecraft. [1] The name Puck follows the convention of naming Uranus's moons after characters from Shakespeare. The orbit of Puck lies between the rings of Uranus and the first of Uranus's large moons, Miranda.
S/2023 U 1 is an irregular moon of Uranus, since it has a distant and highly elliptical and inclined orbit. Irregular moons are loosely bound by Uranus's gravity because of their great distance from the planet, so their orbits are frequently perturbed by the gravity of the Sun and other planets.
