Jupiter is the Solar System’s largest planet, a gas giant with a dense, metallic core and layered cloud bands. Though it lacks a true surface, scientists define a “surface” at the atmospheric depth where pressure matches Earth’s sea‑level pressure.
At this level, the temperature is uniformly around -145 °C (-234 °F), a chilling environment far colder than most places on Earth.
Deep beneath the clouds, Jupiter’s core is estimated to reach about 24,000 °C (43,000 °F), hotter than the surface of the Sun itself. The extreme pressure and gravitational compression generate this intense heat.
Considering the temperature gradient from the defined surface to the core, the mean temperature inside Jupiter averages roughly 12,000 °C (21,500 °F).
