> The new research has revealed that the system ["TOI-178, a star some 200 light-years away in the constellation of Sculptor"] boasts six exoplanets and that all but the one closest to the star are locked in a rhythmic dance as they move in their orbits. In other words, they are in resonance... A similar resonance is observed in the orbits of three of Jupiter's moons: Io, Europa and Ganymede.
