How cold can Uranus get?
speeds on Uranus range from 90 to 360 mph and the planet’s average temperature is a frigid -353 degrees F. The coldest temperature found in Uranus’ lower atmosphere so far is -371 degrees F., which rivals Neptune’s frigid temperatures. Findings from Hubble reveal that clouds circle Uranus at over 300 mph.
