What Is the Hottest Temperature on Jupiter?

Scientists speculate that the core of Jupiter may reach temperatures of 35,700 degrees Celsius, which is hotter than the temperature on the sun's surface. The highest recorded temperature on Jupiter is 40 degrees Fahrenheit, near the planet's equator.

Jupiter is actually very cold averaging temperatures of minus 128 degrees to minus 148 degrees Celsius at the surface of the atmosphere. Jupiter's atmosphere does not have clearly identifiable boundaries, as it is basically a giant ball of various gases such as hydrogen, helium, methane and ammonia with no solid surface of rock. Juno, a spacecraft specifically built to explore Jupiter, will reach the planet in 2016, according to NASA.
