Learn more about the Orbiter
A Tellurium Orbiter is a model of the sun and earth orbit.
Each issue of Build a Model Earth, Moon & Sun Orbiter comes with the components you need to build a modern version of a classical tellurion – an accurate working model of the Earth, Moon and Sun system, designed to predict solar and lunar eclipses and demonstrate the rotation and orbits of Earth and the Moon.
There are three stages in the construction of your solar system model. Assembly instructions are provided for each sub-stage.
Each issue comes with the components you need to build this modern interpretation of a classical orrery as well as a collector’s magazine, full of in-depth features and stunning space images.
