Javascript Jupiter/CC

This is a modified version of JavaScript Jupiter by Akkana Peck.

Here are the four bright "Galilean" moons of Jupiter -- Io, Europa, Ganymede and Callisto -- and their shadows. It also shows the position of Jupiter's "great red spot" (GRS).

North is up; west is right (binocular/Newtonian view, not refractor).

The moon positions are set using Javascript, which is disabled in your browser. You'll need to turn it back on if you want to see the current position of Jupiter's moons.
