The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
Instead, proper or mean orbital elements are used to describe the long-term orbits of irregular moons more accurately, since these are calculated by averaging out the perturbed orbit over a long period of time. [7]: 4 Over an 800-year time span from 1600 to 2400, S/2023 U 1's average semi-major axis or orbital distance from Uranus is 7.98 ...
Uranus has at least one horseshoe orbiter occupying the Sun–Uranus L 3 Lagrangian point—a gravitationally unstable region at 180° in its orbit, 83982 Crantor. [154] [155] Crantor moves inside Uranus's co-orbital region on a complex, temporary horseshoe orbit. 2010 EU 65 is also a promising Uranus horseshoe librator candidate. [155]
NASA’s Voyager 2 flyby in 1986 provided the only close-up look at Uranus. Nearly 40 years later, scientists are looking back at this data and finding out the visit happened during a strange ...
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy , it usually applies to planets or asteroids orbiting the Sun , moons orbiting planets, exoplanets orbiting other stars , or binary stars .
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. [3] William Herschel discovered the first two moons, Titania and Oberon, in 1787.
NASA scientists say Uranus' rings have only been captured by two other cameras. They were first scoped out by the Voyager 2 spacecraft as it flew past in 1986. Later, the Kec.
