Moons of Jupiter

This 3D simulator shows you the motion of Jupiter and of its four Galilean moons, completing our previous app named Planets. You can observe Jupiter`s Great Red Spot and the smaller Jovian storms in high resolution, as well as the surface features of the moons. Imagine you are traveling in a fast spaceship that can orbit the planet and its moons, directly observing their strange surfaces. The four Galilean moons are: Io, Europa, Ganymede, and Callisto; they were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun.
This app is mainly designed for tablets (landscape orientation is recommended), but it works fine on modern phones too (Android 6 or newer).
