The coldest planet in the Solar System is Uranus, which holds the record for the lowest temperature ever measured in the solar system at a chilly -224°C (minus 371°F)
. Although Uranus is closer to the Sun than Neptune, it is still colder due to its unique characteristics. One suggestion for its coldness is that convection in its atmosphere is inhibited, preventing large-scale heat distribution
. Another possibility is that Uranus lost most of its primordial heat early in its life
. Its highly tilted axis, which is over 97°, also contributes to its coldness
. While Uranus is the coldest planet in the Solar System, other planets like Neptune and Jupiter are also extremely cold, with temperatures ranging from -214°C to -238°C
