This orrery's style is very ancient and was used for teaching since 18th century.This orrery can vividly show the solar system we live in,
very smartly designed and perfectly manufactured. The gears's ratios are precisely calculated,which make the model matches the movements of
the real planets.The relative speed of each planet,distance,appearance and many other features simulate the real solar system very well.
Almost assemblied,you just need to assembly the planet and the three feet,which is very easy to do.This orrery will be the best artwork you ever buy.
The model motor is powered by a 6V DC power adapter.It has a speed controler knob to base.
Some of other great features:

Q:What's the speed of the planets?
A:Normally the earth'period of revolution is about 42 seconds,and you can calculate other planets' period ,since the ratio of the speeds of the planets is as the reality.In fact,there's a little speed controler at the bottom,and you can regulate the speed.
Q:Is it's speed of the earth as the real or is faster?
A:On the case of angular velocity,Faster.If it's angular speed is as the real,you can't see it moving.
Q:the orbits of the planets are circular or oval?
A:Circular.Althought in the reality they are oval,but make them in a mechanical model is not easy,and according to my knowledge,any other orrery in history doesn't meet this requirement.Maybe we will consider this in future.
