This is a very good quality antique style mechanical orrery,also called solar system model.As many of us knows,orrery is evolved from the antikythera instrument,which is a mystery and hot topic for many archaeologists and amateur astronomers.You can find out many articles about antikythera mechanism in internet.Orrery inherited many of the features of antikythera instrument,such as complex mechanism and mechanical/gear transmission,accurate simulation of the real solar system.If you can't get a antikythera instrument--of course you can't:),then maybe you'd like to have this high quality brass orrery.
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 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.
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

-----What's the speed of the planets? 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.
-----Is it's speed as the real or is faster? Faster.If it's speed is as the real,you can't see it moving,but the ratio of the periods of the planets is very accuratly as the real.
-----the orbits of the planets are circular or oval? 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.
----- Will it break during travel? Normally it doesn't,and we have ship this assemblied orrery for many times.We package it in customizing poly velvet box.
