Moons of Jupiter

A nice 3D simulation of the four Galilean moons of Jupiter in high definition

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).
