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 temperature falls from about 320 K (47 °C; 116 °F) at the base of the nominal troposphere at −300 km to 53 K (−220 °C; −364 °F) at 50 km. [98] [101] The temperatures in the coldest upper region of the troposphere (the tropopause) actually vary in the range between 49 and 57 K (−224 and −216 °C; −371 and −357 °F ...
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 ...
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 .

194.7 K, sublimation temperature of dry ice; 273.15 K (0 °C), melting point of bound water; 273.16 K (0.01 °C), temperature of triple point of water; c. 293 K, room temperature; 373.15 K (100 °C), boiling point of bound water at sea level; 647 K, critical point of superheated water; 737.5 K, mean on Venus
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 ...
A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...
