As a research assignment for a science class, a student has been asked to determine how many times Io revolves around Jupiter in one Jupiter year. To help answer this question, he has gathered the following facts from the library:

The same side of Io always faces Jupiter.Io’s period of rotation on its axis is 1.8 Earth days.One Jupiter year is equal to 12 Earth years.

By using this information and by performing a few calculations, the student should be able to complete the assignment.

What can you conclude about Io’s period of revolution around Jupiter? A.It is less than its period of rotation.B.It is equal to its period of rotation on its axis.C.It is greater than its period of rotation on its axis.D.It is equal to one Jupiter year.

5

B. It is equal to its period of rotation on its axis.

(Just like the Earth’s moon! The rotation and revolution period take the same amount of time-- about a month)
