Watch how these 6 planets orbit their star in perfect sync

Astronomers have observed a solar system where six planets are in perfect sync with each other as they dance through space around their star, a rare find in the galaxy.

About 100 light-years away in the northern constellation of Coma Berenices, these exoplanets, studied with NASA and other telescopes, are in a gravitational lockstep likened to a waltz. To demonstrate the precise timing kept by the orbits of these worlds, researchers have created an animation of the system set to music.
