You can't really give a single "average temperature" for Jupiter because it doesn't have a solid surface like Earth. It's a gas giant with a core that's incredibly hot, but the temperature in its atmosphere varies drastically depending on altitude and location.

Here's a breakdown:

* Top of the atmosphere (tropopause): Around -234 degrees Fahrenheit (-148 degrees Celsius)

* Deep within the atmosphere: Temperatures rise as you go deeper, reaching thousands of degrees Fahrenheit.

* Core: Estimated to be over 43,000 degrees Fahrenheit (24,000 degrees Celsius)

So, while the top of Jupiter's atmosphere is incredibly cold, it's important to remember that it's just the tip of the iceberg, so to speak.
