origincompositionatmosphereringsNumerical modelling of the gravitational capture and contraction of Uranus' primitive atmosphere with the modern laplacian theory, suggests that the four outer moons consist mostly of frozen methane and have densities 0.53 g/cm 3.

The atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons. Methane in the upper atmosphere absorbs red light, giving Uranus its blue-green color. The atmosphere is arranged into clouds running at constant latitudes, similar...

in their bulk densities—1.285 and 1.64 grams per cubic cm, respectively—reveals a fundamental difference incompositionand internal structure. Although Uranus and Neptune are significantly larger than the terrestrial planets, their radii are less than half those of the largest planets,JupiterandSaturn....
Visible-to-near-infrared observations indicate that the cloud top of the main cloud deck on Uranus lies at a pressure level of between 1.2 bar and 3 bar. However, its composition has never been unambiguously identified, although it is widely assume
Uranus' atmospheric composition by volume is 82.5% hydrogen, 15.2% helium and 2.3% methane. Its internal structure is made up of a mantle of water, ammonia and methane ices, as well as a core of iron and magnesium silicate. Uranus' average distance from the sun is roughly 1.8 billion...
英文:Uranus has a unique blue color because its atmosphere contains methane. 中文:科学家们对天王星的研究帮助我们更好地理解了太阳系的构成。 英文:Scientists' research on Uranus has helped us better understand the composition of the solar system. 英文同义表达: 第一条:无直接同义词...
Composition:The planet Uranus is believed to have a rocky core and is composed of 83% hydrogen, 15% helium, and 2% methane. It is the methane gas above the cloud layers which gives the planet its blue-green color. Along withNeptune, Uranus is called an “ice-giant,” and with a minim...
Atmospheric composition by volume: Molecular hydrogen: 82.5 percent Helium: 15.2 percent Methane: 2.3 percent Layering in the atmosphere As on Earth, the atmosphere ofUranusis broken into layers, depending upon temperature and pressure. Like the other gas giants, the planet doesn't have a firm su...
The outer Solar System presents an astoundingly diverse panorama. The fourgiant planetssubdivide naturally into two classes, Jovian and Uranian. TheJovian planets, Jupiter and Saturn, which are not very far from the composition of the Sun or of otherPopulation I stars, together have more than 10...
