Jupiter doesn't experience "night" in the same way Earth does. It doesn't have a solid surface like Earth, and its internal heat source keeps it incredibly hot.

Here's why:

* No real night: Jupiter's atmosphere is constantly rotating, so there's no dark side like Earth.

* Internal heat: Jupiter generates its own heat due to gravitational pressure, making it much hotter than it receives from the Sun.

* Temperature variations: Jupiter's atmospheric temperatures vary depending on altitude, with the upper atmosphere reaching extremely low temperatures (-234°F or -148°C). However, the deeper you go, the hotter it gets. The core is thought to be around 24,000°F (13,300°C).

So, while Jupiter's upper atmosphere experiences very low temperatures, its internal heat means it's extremely hot deep down.
