Large Object Orrery

This
Orrery demonstrates all the known objects in our Solar System larger
than 250km diameter.
It
consists of seven units, each of which can be built as a standalone
model, and all units can be interconnected with periods of motion
related within an accuracy of 1%.
The
Units
-
The Sun rotating; the inner Planets (Mercury,
Venus, Earth, Mars) rotating and also revolving around the Sun;
the Moon revolving around the Earth.
-
The Asteroid Belt: This includes the Dwarf
Planet Ceres and the twelve largest Asteroids, all rotating at
the correct relative rate.

-
Saturn rotating, with a representation of its
rings, and its eight largest moons revolving around it.
-
Uranus rotating and its five largest moons

the passage of
‘Orrery Time’.

Nineteen Trans-Neptunian Objects (TNO’s).
These include the Dwarf Planets Pluto (with its Moon Charon),
Eris and Makemake. The TNO 2003 EL61 (Santa) has a large moon
