Show HN: A Solar System Orbital Sim That Lets You Change Your Point of View

A Show HN project offers a solar system orbital simulation that switches the center of rotation to any selected planet, not just the Sun. Users pick a planet from a drop-down to view orbits from its frame of reference, with zoom and pan recommended since the switch happens dynamically in place. Clicking planets hides their traces for a cleaner view, and the Earth-POV view of Venus produces notable epicycles.
