Why is Jupiter hot and cold at the same time?
Hot Jupiters (also called roaster planets, epistellar jovians, pegasids or pegasean planets) are a class of extrasolar planets whose characteristics are similar to Jupiter, but which have high surface temperatures because they orbit very close—between approximately 0.015 and 0.5 astronomical units (2.2×106 and 75×106 km) to their parent stars,while Jupiter orbits its parent star (the Sun) at 5.2 astronomical units (780×106km), causing low surface temperatures.

One of the best-known hot Jupiters is 51 Pegasi b, nicknamed Bellerophon. Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star.

Jupiter is a really big planet, so not all of it is the same temperature. It goes from as cold as -145 degrees C at the top of the clouds to as hot as 36,000 K at the center of the planet, where the pressure and temperature increase dramatically.

Jupiter has an outer temperature , depending on the location within its atmosphere of between 112 Kelvin and 165 Kelvin . Deeper within the layers, pressure causes the temperature to rise to several thousand degrees Celsius.
 The temperatures have never been measured.
