The Full Story
Uranus is usually considered the coldest planet in the Solar System by average atmospheric temperature. Measurements from spacecraft and observations put its cloud tops around 49 kelvin, which is roughly minus 224 degrees Celsius. That makes it colder than Neptune in the average sense, even though Neptune is farther from the Sun. Scientists think Uranus’s unusual internal heat flow may help explain why it is so cold.
