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 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).
The planetoid Orcus will have completed one orbit of the Sun since its discovery in 2004, based upon a barycentric orbital period of 246 Earth years. [63] 2251 March 4 At 10:47 UTC, Venus will occult Uranus. [42] 2253 August 1 Mercury occults Regulus (for the first time since August 13, 364 BC). 2255 June 9 Transit of Venus. 2257

On the other side of Uranus's orbit, the orientation of the poles towards the Sun is reversed. Each pole gets around 42 years of continuous sunlight, followed by 42 years of darkness. [74] Near the time of the equinoxes, the Sun faces the equator of Uranus, giving a period of day–night cycles similar to those seen on most of the other planets.

The north orbital poles of the Solar System major planets all lie within Draco. [1] The central yellow dot represents the Sun's rotation axis north pole. [citation needed] Jupiter's north orbital pole is colored orange, Mercury's pale blue, Venus's green, Earth's blue, Mars's red, Saturn's magenta, Uranus's grey, and Neptune's lavender.
It orbits the Sun between Saturn and Uranus, grazing the orbit of Uranus. On 26 March 2014, astronomers announced the discovery of two rings (nicknamed Oiapoque and Chuí after the rivers that define Brazil's borders) [22] around Chariklo by observing a stellar occultation, [23] [24] making it the first minor planet known to have rings.
