The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the Geostationary Earth Orbit Satellite Model.

This program shows the Moon revolving around the Earth. The model is not real since the example is just to show the new Java 3D-based visualization capabilities of EJS.

Ejs Open Source Earth and Moon Model is by Professor Francisco Esquembre aka Paco for which this resource is created/remixed from.
thanks Prof Paco!

this is shared model in the OSP digital library.
thanks to Prof Paco for EJS and an earlier model that is resource is based on.
