Reply to comment by jmens14 in What's the importance of our solar system having so many moons? by [deleted]

It would actually be cool to live on a Jupiter moon and see Jupiter in the sky covering 1/4 of it.

I know diatances are way too big and Jupiter is still small seen from the moons but still

I too wish to live on a moon orbiting a gas giant.

I mean, we live in a planet orbiting a gas giant that just happened to have achieved fusion. So it's not that far fetched

Do you know if Jupiter gives off any "heat"? Is it possible that Jupiter, though not creating fusion actually can result in a moon that has enough energy within the Jovian system to create a satellite that can result in temperatures that are conducive to life.

I believe the moon Io experiences enough gravitational influence that it keeps it's core molten

Tidal heating is a thing. Jupiter does do a bit of that to it's moons but it's moons also do that to each other.

Apparently per random internet searching, Jupiter gives off about twice as much energy as it absorbs from the sun.

The radiation belts of Jupiter make living on its moons no fun at all! Not to mention it’s strong gravity stretches and pulls everything

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.
