Does Io rotate on its axis?

Answer 1

According to the best data available today, "Io" moves in an orbit averaging 262,000 miles from Jupiter. Just like earth's moon, Io's axial rotation and orbital revolution are in sync. Both periods are 1.769 earth days.

Answer 2

Io takes 42.5 hours to make one orbit of Jupiter. It is a tidally locked moon, meaning that one face is always facing Jupiter. It's will therefore rotate approximately once on it's axis in that time also.

Answer 3

Yes, Io does rotate on its axis, just like all other celestial bodies. It rotates once on its axis for every orbit around Jupiter, which is why one side of Io always faces Jupiter. This is known as synchronous rotation.

Answer 4

In the time it takes Pluto to do a full rotation (a day), the Earth has done 6.4 rotations around itself (meaning for every day on Pluto, 6 and a half days pass by on Earth).
