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 ...
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 major moons have almost exactly the same rotational axial tilt as Uranus (their axes are parallel to that of Uranus). [2] The Sun would appear to follow a circular path around Uranus's celestial pole in the sky, at the closest about 7 degrees from it, [c] during the hemispheric summer. Near the equator, it would be seen nearly due north or ...
Conservationists released the pair into a seminatural 3-hectare enclosure in Kazakhstan’s Ile-Balkhash State Nature Reserve in early November. Lunar update The moon has some new stories to share.
No spacecraft other than Voyager 2 has flown by our seventh planet from the sun. Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings.
Near-Earth asteroid (285263) 1998 QE 2 will pass Earth at a distance of 0.038 AU (5.7 million km; 3.5 million mi). [61] 2221 Triple conjunction of Mars and Saturn: 2223 December 2 At 12:39 UTC, Mars will occult Jupiter, this comes after a gap of 836 Earth years. [31] [42] 2227 Pluto's orbit takes it closer to the Sun than Neptune. [62] 2238/2239
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 ...
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 perturbations, S/2023 U 1's orbital elements fluctuate over time: its semi-major axis can range from 7.97 to 7.98 million km (4.95 to 4.96 million mi), eccentricity ...
