The Planeterrella III

A third version of the Planeterrella was completed in November 2012. The Planeterrella III incudes a camera which can move in all degrees of freedom. The main motivation is that the Planeterrella became so popular that it is often shown to more than 100 people at a time. Another motivation comes from a new artistic development: artists begin mounting a show in which the Planeterrella will be on stage. In Planeterrella III, everything is ready for the spheres to rotate around themselves so that it is possible to imagine the auroral ovals rotating with the magnetic field tilted, or the stellar corona moving with the star. In the longer term, improvements will include the use of electromagnets instead of permanent rare earths ones. The pace of these changes depends largely on funding
