The lowest temperature recorded in Uranus's tropopause is 49 K (−224.2 °C; −371.5 °F), making Uranus the coldest planet in the Solar System. [ 18 ] [ 95 ] One of the hypotheses for this discrepancy suggests the Earth-sized impactor theorised to be behind Uranus's axial tilt left the planet with a depleted core temperature, as the impact ...
It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224.2 °C), and has a complex, layered cloud structure with water thought to make up the lowest clouds and methane the uppermost layer of clouds. The interior of Uranus is mainly composed of ice and rock.
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).
Voyager 2's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years, according to a new study. Voyager 2 is the only craft to visit Uranus. Its ...
Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings. Images of which were captured in rich detail last year by the James Webb Space Telescope .
S/2023 U 1 is the smallest and faintest natural satellite of Uranus known, with a diameter of around 8–12 km (5–7 mi). It was discovered on 4 November 2023 by Scott S. Sheppard using the 6.5-meter Magellan–Baade Telescope at Las Campanas Observatory, Chile, and later announced on 23 February 2024. [1]
The width of the narrow component is 4.1–6.1 km and the equivalent depth is about 2.2 km, which corresponds to a normal optical depth of about 0.3–0.6. [24] The ring's broad component is about 10–12 km wide and its equivalent depth is close to 0.3 km, indicating a low normal optical depth of 3 × 10 −2 .
It was located at the latitude of about 28 ± 1° and measured approximately 2° (1300 km) in latitude and 5° (2700 km) in longitude. [5] The feature called Uranus Dark Spot (UDS) moved in the prograde direction relative Uranus's rotation with an average speed of 43.1 ± 0.1 m/s , which is almost 20 m/s faster than the speed of clouds at the ...
