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 ...
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 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 ...
Uranus is the butt of a lot of jokes, but scientists pronounce the name of our seventh planet differently than, say, most giggling middle-schoolers. You've been pronouncing 'Uranus' wrong your ...
The ice giants Uranus and Neptune live up to their name. Although humans have only ever sent one spacecraft (Voyager 2) toward these far-flung worlds, scientists have a pretty good idea that these ...
The furthest two planets in the Solar System both have similar masses, sizes, and atmospheric compositions, but they are different shades of blue. Scientists can finally explain why Uranus and ...
Close correlation between the effective temperature and equilibrium temperature of Uranus can be taken as evidence that processes producing an internal flux are negligible on Uranus compared to the other giant planets. [27] Earth has insufficient geothermal heating to significantly affect its global temperature, with geothermal heating ...
The planet Uranus and its five biggest moons may not be the sterile worlds scientists have long thought. ... It is among the coldest of all the planets. It is also tilted on its side compared to ...
