The Helios Planetarium gives a clear visualisation of the six classical planets (Mercury - Saturn) orbiting at their correct relative speed and stars remaining in their positions in the sky.

The geared, electric orrery will delight keen astronomers of all ages and is available in three versions.

All versions of the model (0142, 0150 and 0151) enable the study of the following topics:

The Planets in their orbits (length of a year, inferior and superior planets)

The phases of Venus

The Moon and its phases (external light source required)

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?

With the large Earth and Moon accessories that are included in versions 0150 and 0151 you can also watch as the Earth rotates on its axis while the Moon orbits it every 29.5 'days'.

Using an external light source (torch, projector), the larger size of Earth and Moon enables you to demonstrate the following events much more clearly:

Day and night

Shadows and the seasons

The Moon's month, phases and eclipses

The Pole Star, circumpolar stars and a nocturnal

The Moon and stars from different positions on Earth

The tides

Space travel

Submitted by: Martin Martin Gross (31/05/2020)

I bought this in May 2020. It says the booklet was revised in 2019. Yet Appendix 2,Setting Longitudes for the planets is from 2006 till 2021? Please update the booklet and send me a new appendix 2. You should have some type of container to keep the spare parts in when not in use.

Response from Cochranes: Thank you so much for taking the time to review our products and for you custom. Edit (July 2020): We are happy to have sent you a new appendix and updated the book and passed your comment on the container for the spare parts to our product team. We hope to see you again soon!
