orrery
The Orrery is a virtual orrery initially built for worldbuilding purposes. It contains a quasi-accurate model of the solar system. Distance isn’t (yet) to scale and the positions of the celestial bodies are incorrect, but the orbital speeds and relative sizes are approximately correct. 1

| width | canvas width in pixels |
| height | canvas height in pixels |
| bg | canvas background colour |
| fg | canvas foreground (stroke) colour |

| id | identifier |
| tether | another optional Body to orbit around of |
| r | radius |
| v | orbital velocity |
| or | orbital radius 2 |
| rs | rotation speed |
const system = new Model()
const orrery = new Orrery({
width: 800,
height: 500,
bg: '#030303',
fg: '#e4e4e4',
model: system,
})
orrery.render()
