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.
With temperatures dropping to -218Â°C in Neptune's upper atmosphere, the planet is one of the coldest in our Solar System. And like all of the gas giants, Neptune has a much hotter core, which is around 7,000Â°C.uch like the other gas giants in our Solar System, the core of Uranus gives off far more heat than is absorbed from the Sun. However, with a core temperature of approximately 4,737 Â°C, Uranus' interior gives of only one-fifth the heat that Jupiter's does and less than half that of Saturn.
