a Grand Planetarium on my Ceiling

This planetarium gets planet positions from NASA daily at midnight and aligns them without complex gears. A motor rotates Mercury, triggering a chain reaction among the other planets. This slow process is shown as a 30x timelapse in the video, taking 1.5 hours in real-time. The Sun houses the motor and other components, and the planetarium's diameter is 2.1 meters. There are also extra gears for the Moon's rotation.
