Show HN: A simple Solar system orbital SIM that permits change of POV

Vibe-wrote to check orbit views from different planets' frame of reference, in addition to the Sun. Selecting the planet from drop-down switches to it as the instantaneous center of rotation. Switches in place, dynamically (I liked it that way better) so recommend use of Zoom+Pan. Click on the planets to hide traces and have a clean screen to focus on particular orbits. Epicycles were expected, but one of Venus from Earth POV is fascinating, in particular. Rest self-explanatory, made to work reasonably on phones. Data derived from https://ssd.jpl.nasa.gov/planets/approx_pos.html.

Initial drive was to visualize the solar system as a binary star system centered on Sol-Jupiter barycentre, but that was not as impressive as imagined. ;>
