whose
Whose law explains the four Galilean moons orbiting Jupiter with periods tied to their distance from the planet?
This is Kepler's law of planetary motion, formulated by Johannes Kepler. It explains orbital periods using the size of the orbit, and it is central to understanding the Galilean moons too.
