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]
Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on ...
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 .
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 ...
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 ...
Its unusual tilt makes Uranus appear to orbit the sun like a rolling ball. Uranus, which orbits almost 20 times further from the sun than Earth does, has 28 known moons and two sets of rings.
C/2014 UN 271 came from the Oort cloud and has been inside of the orbit of Neptune (29.9 AU) since March 2014 and passed inside the orbit of Uranus (18.3 AU) in September 2022. [k] [16] [40] The time of perihelion has been well-known since June 2021. [6] The current 3-sigma uncertainty in the comet's distance from the Sun is ±35,000 km. [16]
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 ...
