Model of the solar system.

Earth group planets and giant planets:
-Mercury;
-Venus;
-Earth (+ moon)
-Mars;
-Jupiter;
-Saturn;
-Uranus;
-Neptune.

All planets are made in proportion to each other and have correct deviations from the vertical axis.
The planet of the earth goes in a couple with his satellite which is proportional to earth and is at a real distance from planet.
The moon is linked to the earth that is rotating the earth – the moon rotates with it. In order to rotate the moon separately
just select it and make a turn (the pivot of the month is in the center of the earth)

Be careful the objects in the scene are quite large but you can easily scale them to the required size.
