Our company is the original factory of the orrery 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 orrery needs.
This is a very good quality
antique style mechanical orrery,also called 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 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:
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.
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
