A atmosfera de Urano, embora similar às de Júpiter e Saturno em sua composição primária de hidrogênio e hélio, contém mais "gelos" tais como água, amônia e metano, assim como traços de hidrocarbonetos. [ 8] É a mais fria atmosfera planetária no Sistema Solar, com uma temperatura mínima de 49 K (–224 °C ).
Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small rocky core. Near the core, it heats up to 9,000 degrees Fahrenheit (4,982 degrees Celsius).

Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years.
Jan 17, 2017 · The planet Uranus was so hard to find in part because it is a whopping 1.8 billion miles away. But it is actually the third-largest planet in our solar system, and is roughly four times wider than ...
Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called 'ice' or volatiles.
