Two Questions: If it takes Jupiter 9.9 hours to make one rotation around the earth. This means that one day on Jupiter is actually how long? This is as many as how many Earth days?

See other post.

Jupiter makes a rotation around Earth? Since when? Here in Texas, I haven't noticed it.

An Earth day is 24 hours, because it rotates on its own axis once each 24 hours. So how long now is a day on Jupiter?

To determine how long one day on Jupiter is, we need to know how long it takes for Jupiter to complete one rotation on its own axis. The given information states that it takes Jupiter 9.9 hours to make one rotation around the Earth, but this is not directly related to Jupiter's rotation period.

The rotation period of Jupiter is approximately 9.9 Earth hours. This means that Jupiter completes one full rotation on its own axis in 9.9 Earth hours. Therefore, one day on Jupiter is approximately 9.9 Earth hours long.

To find out how many Earth days are equivalent to one day on Jupiter, we need to divide the length of a Jupiter day by the length of an Earth day.

Knowing that there are 24 Earth hours in a day, we can perform the calculation:

(9.9 Earth hours) / (24 Earth hours) ≈ 0.4125 Earth days

So, one day on Jupiter is equivalent to approximately 0.4125 Earth days.
