The project plan

Before we begin implementing the project, it will help if we first define what we're going to do, identify the assets we will use, and make a plan.

The goal of this project is to show a model of the solar system that illustrates the relative position, size, and rotation speeds of the nine planets.

User experience

Users should be able to open our solar system app and see a model of the sun, earth, moon, and the other eight planets rotating as expected. Each body should look reasonably realistic using texture images from NASA and should be scaled proportionally, keeping in mind the diameter, spin rate (day), and orbit (year). The planets will orbit the sun and be illuminated by it.

Using custom cards for each planet, the user will be able to point their camera at a card to zoom in on that specific planet. The user should also be able to watch the bodies move in fast or slow motion. Finally, the app should play background music while it runs.

Because the actual scale of the solar...
