At closest approach, I wonder how high you'd have to launch/propel something for it to leave the gravity well of your tiny moon and be sucked into the terrifying vortex of the gas giant. (Come to think of it, how weak would gravity seem on a moon no more than a couple of miles across? How high would you be able to jump and how long would it take to float back down? The mind boggles!)

Im more interested in thinking about the difference between jumping from the far side of that moon, or from a point along the plane perpendicular to Jupiters acceleration.

"Caution: Jumping more than 20 feet off the ground may cause you to cross out of Io's orbit and into Jupiter's, and you will never land on Io again."

That'd be a world without high jump events.
