Solar System Sandcastle Example

I just noticed that all the planets are actually present in cesium along with the moon - it would be an awesome demo if while viewing earth the other planets were highlighted / labeled and if you clicked on them you "zoomed" to them by either manual movement or switching out earth with the sizing/shape/ellipsoid of whatever planet was clicked or at least showed the label of which planet is which - since currently there's nothing highlighting this feature

Locate the relevant Cesium Sandcastle example and the code that creates the planet and moon ellipsoids. Run the demo and inspect how entities are displayed and selected before clarifying which labeling, highlighting, and navigation behavior should be implemented. Done means a documented interaction choice is implemented and demonstrated in the example.
