How Cold Is the Planet Uranus and What Effects Does Uranus’s Cold Temperature Have On Its Atmosphere?

Voyager 2 registered a nearly consistent temperature of –155°F (-221°C) on Uranus.

Strong winds, up to 180 miles (288 km) per hour, that blow in the same direction as Uranus rotates keep the temperature steady all around the planet.

The cold is responsible for our inability to see any surface detail on this pale blue planet.

The atmosphere is similar to Jupiter’s and Saturn’s atmospheres: 85 percent hydrogen, 13 percent helium, and 2 percent methane.

But the cold temperatures on Uranus create a low, dense smog covering the typically stormy atmosphere and the planet’s surface.
