The lowest temperature recorded in Uranus's tropopause is 49 K (−224 °C), making Uranus the coldest planet in the Solar System, colder than Neptune. [ 22 ] [ 23 ] Another hypothesis states that when Uranus was "knocked over" by the supermassive impactor which caused its extreme axial tilt, the event also caused it to expel most of its ...
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 ...
Temperature profile of the Uranian troposphere and lower stratosphere. Cloud and haze layers are also indicated. The Uranian atmosphere can be divided into three main layers: the troposphere, between altitudes of −300 [a] and 50 km and pressures from 100 to 0.1 bar; the stratosphere, spanning altitudes between 50 and 4000 km and pressures between 0.1 and 10 −10 bar; and the thermosphere ...
The planet Uranus and its five biggest moons may not be the sterile ... It is among the coldest of all the planets. It is also tilted on its side compared to all the other worlds – as if it had ...
An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. ... Voyager 2's flyby may have taken place at the same time that some unusual space weather was squashing the planet's ...
In 1986, Nasa’s Voyager 2 flew by the seventh planet in the Solar System, providing scientists with their first and only glimpse of Uranus, and shaping their understanding of it since.
Planets from the Solar System were also included for comparison purposes. Discovered in 2006, OGLE-2005-BLG-390Lb is the coldest known exoplanet, and was nicknamed "Hoth" by NASA in reference to the planet from the Star Wars franchise. [1]
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 .
