Physical Characteristics [edit]
Until recently it was thought that all the planets be classified as a gas giant planets are built similarly, but research using space probes have shown that the structure and chemical composition of Uranus largely distinguish it from Jupiter and Saturn. First of all uranium contains relatively little hydrogen - 15%, and only a small admixture of helium (these elements are major components of larger planets). Its mass is about 14 Earth masses. It is the lightest of the gaseous planets. Has a much colder core than the other gas planets in space and radiates very little heat. Internal structure
[edit]
In the center of Uranus is probably a small rocky core, bringing together approximately 24% of the planet. It is surrounded by a thick coat composed of ice, solidified ammonia and methane (65%). The remaining 11% is the liquidity-gas shell surface, which passes gradually into the atmosphere, consisting of 83% hydrogen and 15% helium and at lower altitudes and with methane (2%) and ammonia, often forming clouds.
distinctive turquoise hue gives Uranus admixture of methane contained in the atmosphere, which absorbs red color.
