Uranus is an oblate spheroid, which causes its visible area to become larger when viewed from the poles. This explains in part its brighter appearance at solstices. [16] Uranus is also known to exhibit strong zonal variations in albedo (see above). [10] For instance, the south polar region of Uranus is much brighter than the equatorial bands. [3]
The furthest two planets in the Solar System both have similar masses, sizes, and atmospheric compositions, but they are different shades of blue.
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 ...
Neptune, which is Uranus's near twin in size and composition, radiates 2.61 times as much energy into space as it receives from the Sun, [23] but Uranus radiates hardly any excess heat at all. The total power radiated by Uranus in the far infrared (i.e. heat) part of the spectrum is 1.06 ± 0.08 times the solar energy absorbed in its atmosphere .
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 ...
Unlike the other giant planets, Uranus has an extreme tilt that causes its seasons to be severely pronounced. The two planets also have other subtle but important differences. Uranus has more hydrogen and helium than Neptune despite being less massive overall. Neptune is therefore denser and has much more internal heat and a more active atmosphere.
Scientists have finally discovered how sheets of diamond rain form on the ice giants, Neptune and Uranus. The answer could explain why Neptune’s core is hot.
