🪐 Exoplanet Moons - 2D Orbit Map

2D companion of the 3D exoplanet-and-moons scene: a top-down map of four moons that compares the 3D page's hand-picked constant speeds with physical leapfrog orbits, with period readouts, a log-log omega-radius plot, a T squared over a cubed check and optional mutual gravity.
