As an ancient astrolabe constructed, gives the app a beautiful recycled impression of our solar system. One can observe the galactic mechanics "from the outside" or to move freely in the solar system. Individual planet or moon can visit even to throw from the surface of a look at the planetary and stellar neighborhood. Even if the proportions and distances shown are not to scale, of course, so you can even get an impression of how a solar or lunar eclipse occurs. If you now throw more of the Saturn surface a look at his rings, or could see dancing the moons of Jupiter, bout absolutely perfect !!!
