Our company is the original factory of the solar system model of this type,who has been engaged in manufacturing orreries and the planetary gears for more than ten years.Basically the orreries of this outlook all come from our company.We and several other companies(mainly produce the colored planets) nearby cooperate together to manufactur all the parts an model needs.
This is a very good quality antique style mechanical solar system model,and it was already assemblied and ready-to-work.It's new and unused.The plantes it contains is compete,even includes the celestial bodies Ceres and Eris as well as including Pluto.By the way,Ceres is the firstly found Asteroid by mankind,Eris is the latestly found Asteroid,in 2005,and Pluto was expelleded from the family of planets in 2006,because it's too small.
This model's style is very ancient and was used for teaching since 18th century.This model 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.
Some of other great features:
(1)In this item,the earth'period of revolution is about 42 seconds,and you can calculate? other plants' period ,since the ratio of the speeds of the planets is as the reality.
(2)the sun and the earth can rotate itself,which is as the real natural phenomenon,and the self-rotating speed relative to simulates the reality, too.
(3)there's still other great features I don't talk about here. We do our best to make it perfect in many other details of this item
