Helios Orrery and Northern Hemisphere Star Dome
A complete fully-electric system for studying the planets and stars.This model can be set up as either the basic orrery or the orrery with the star dome (northern hemisphere).
Look through the dome to see the stars visible from earth for your latitude and time of year. See how the stars and constellations have fixed locations in space whilst the planets orbit the Sun. The dome shows all 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
- Time - solar, sidereal and G.M.T.
- Eclipse basics
- How the planets appear to move against the night sky
- The ecliptic and the Zodiacal constellations
- Use of the Helios outside at night - where should the stars appear in the sky?
Customers interested in the Southern hemisphere can purchase this dome separately (Product reference: 0159) or purchase the complete Helios Planetarium for the Southern hemisphere (Product reference 0151).
