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.
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 ...
Margaret, the only known irregular moon of Uranus with a prograde orbit, is shown in light grey. The orbits and mean distances of the irregular moons are variable over short timescales due to frequent planetary and solar perturbations , therefore the listed orbital elements of all irregular moons are averaged over a 8,000-year numerical ...
Nasa’s Voyager 2 flyby in 1986 provided the only close-up look at Uranus. Nearly 40 years later, ... Uranus is still an oddball, rotating sideways and taking 84 years to orbit the Sun.
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 .
Orbit diagram of C/2014 UN 271 's near-parabolic trajectory passing perpendicularly through the outer Solar System. 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.
Chariklo lies within 0.09 AU of the 4:3 resonance of Uranus and is estimated to have a relatively long orbital half-life of about 10.3 Myr. [31] Orbital simulations of twenty clones of Chariklo suggest that Chariklo will not start to regularly come within 3 AU (450 Gm) of Uranus for about thirty thousand years. [32]
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 ...
