Cochranes Of Oxford Helios Orrery and Star Dome

This Helios Orrery and Star Dome model from Cochrane's can be set up as either a basic orrery or an orrery with a star dome. Look through the dome to see the stars visible from earth for your latitude and the time of year. See how the stars and constellations have fixed locations in space and how the planets orbit the Sun. The dome shows all the major stars and constellations around the ecliptic and over the Northern hemisphere.

The following subjects can be studied with the Orrery and Star Dome model:

• The Planets in their orbits (length of a year, inferior and superior planets and more)
• The Moon and its phases
• Eclipse basics
• Time - solar, sidereal and G.M.T. The ecliptic and the Zodiacal constellations
• How the planets appear to move against the night sky
• Use of the Helios outside at night - where should the stars appear in the sky?

Takes 4x D size batteries, not included.
