What is a Jovian Year and Jovian Day?

http://www.enchantedlearning.com/subjects/astronomy/planets/jupiter/

The planet Jupiter orbits the sun once each 4,332.7 days.

A Jovian day is about 10 of our hours.

A Jovian Year is a year on Jupiter and Jovian Day is a day on Jupiter all in terms of Earth time.

Jovian Year=11.862 Earth yrs
Jovian Day=9.925 Earth Days.
Hope this helps. Peace

A Jovian year and Jovian day refer to the orbital and rotational periods of Jupiter, respectively. To understand what a Jovian year and day are, we need to know a bit about Jupiter itself.

Jupiter is the largest planet in our solar system and takes about 11.86 Earth years to complete one orbit around the Sun. This means that its orbital period, or Jovian year, is approximately 11.86 Earth years.

On the other hand, Jupiter is a gas giant that rotates rapidly on its axis. It completes one full rotation in about 9.9 Earth hours. This rotational period is referred to as a Jovian day.

Now, to calculate the Jovian year and Jovian day, we can use the conversion factors between Earth and Jupiter's time scales.

To determine the Jovian year, we divide Jupiter's orbital period by Earth's orbital period around the Sun. Since Jupiter's orbital period is approximately 11.86 Earth years, the Jovian year is equivalent to 11.86 Earth years.

To find the Jovian day, we divide Jupiter's rotational period by Earth's rotational period. Given that Jupiter's day is about 9.9 Earth hours, the Jovian day is roughly equivalent to 9.9 Earth hours.

So, in summary, a Jovian year is the time it takes Jupiter to complete one orbit around the Sun, approximately 11.86 Earth years. A Jovian day, on the other hand, is the time it takes Jupiter to rotate once on its axis, around 9.9 Earth hours.
