Highest temperature on Jupiter
The temperature and pressure inside Jupiter increase steadily toward the core. At the phase transition region where liquid hydrogen (heated beyond its critical point) becomes metallic, it is believed the temperature is 10,000 K and the pressure is 200 GPa. The temperature at the core boundary is estimated to be 36,000 K and the interior pressure is roughly 3,000–4,500 GPa.
Surface temperature @ 1 bar = 165K and @ .1 bar = 112K (both mean averages) *
The highest temperature inside Jupiter is 1,000,000 degrees Centigrade.
