Uranus is the coldest ice cream in the shop.
Uranus is the seventh planet from the Sun . It is the coldest planetary atmosphere in the Solar System , with a minimum temperature of 49 K , and has a complex , layered cloud structure with water thought to make up the lowest clouds and methane the uppermost layer of clouds . Uranus is the only planet whose name is derived from a figure from Greek mythology , from the Latinised version of the Greek god of the sky Ouranos . The Uranian system has a unique configuration among those of the planets because its axis of rotation is tilted sideways , nearly into the plane of its solar orbit . In 1986 , images from Voyager 2 showed Uranus as an almost featureless planet in visible light , without the cloud bands or storms associated with the other giant planets .
