click the sun to start, and press space to stop. the orbiting speed is to scale, but the size and distance is not. Uranus and Neptune are not in because there isn't enough space, and they are not visible to the naked eye. I put ceres in the asteroid belt for fun, it doesn't have the actual orbital period of ceres. there isn't enough space for moons
I got inspired by the solar system project by pixel sheep and the solar system watch face on the Apple Watch.
