Jupiter's day is very short, but its year is very long! Here's the breakdown:

* Jupiter's Day: Jupiter spins very fast, completing one rotation in just under 10 hours.

* Jupiter's Year: It takes Jupiter almost 12 Earth years (11.86 years to be exact) to orbit the Sun once.

So, if you're thinking about how many Earth days are in a Jupiter year, it would be approximately 4,333 days.
