* Day (Rotation Period): Jupiter rotates incredibly fast! A single day on Jupiter is only about 9 hours and 55 minutes. This is much faster than Earth's 24-hour rotation.

* Year (Orbital Period): Jupiter takes a long time to orbit the Sun. A Jovian year is 11.86 Earth years. So, if you were living on Jupiter, you'd celebrate your birthday only once every 11 and a half Earth years!
