Although Neptune, the farthest planet from the sun, is pretty damn cold (-360 degrees Fahrenheit), Uranus takes the prize for being our solar systemâs coldest planet. The lowest temperature ever recorded on Uranus was -371 degrees Fahrenheit. Scientists arenât exactly sure why Uranus, which is more than a billion miles closer to our star than Neptune, boasts colder temperatures, but some experts believe the planetâs odd orientation or energetic atmosphere are to blame for the loss of heat.
Uranus's maximum temperature is -300 degrees, while Neptune's average surface temperature can be as low as -370 degrees. Although at one time the ninth planet of the solar system was Pluto, this planet was reassigned to a dwarf planet classification in 2006.
