• Add rings to Saturn. (A cheap way to implement might be a plane with transparency.)

• Improve goToPlanet so that your camera position animates between positions.

• Add controls to allow you to change the perspective or fly freely through space.

• Add a top-down view option, for a "traditional" picture of the Solar System. (Be aware of float precision issues at scale.)

• Add text labels to each planet that use the planet's transform but always face the camera. In lieu of 3D text objects, the labels could be prepared images.

• Add background music.

• Improve the positional accuracy in such a way that it accurately...
