When Voyager 2 flew by Uranus in 1986, it observed a total of 10 cloud features across the entire planet. [115] [116] One proposed explanation for this dearth of features is that Uranus's internal heat is markedly lower than that of the other giant planets, being the coldest planet in the Solar System.

Uranus – seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System . Uranus is similar in composition to Neptune , and both have different bulk chemical composition from that of the larger gas giants Jupiter and Saturn .
Although Uranus is presently largely blank in appearance, it has been historically shown to have occasional features, such as in March and April 1884, when astronomers Henri Joseph Perrotin, Norman Lockyer, and Charles Trépied observed a bright, elongated spot (presumably a storm) circling the equator of the planet.

An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery ...
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
The planet Uranus and its five biggest moons may not be the dead sterile worlds that scientists have long thought. Instead, they may have oceans, and the moons may even be capable of supporting ...
Uranus emits the least heat, one-tenth as much as Neptune. It is suspected that this may be related to its extreme 98˚ axial tilt. This causes its seasonal patterns to be very different from those of any other planet in the Solar System. [2] There are still no complete models explaining the atmospheric features observed in the ice giants. [2]
Uranus's atmosphere is remarkably bland in comparison to the other giant planets which it otherwise closely resembles. [1] [2] When Voyager 2 flew by Uranus in 1986, it observed a total of ten cloud features across the entire planet.
