TOI-178—Music of the Spheres

The exoplanet system TOI-178 in the constellation of Sculptor has six planets orbiting close to a K type orange dwarf star. Five of the planets appear to be locked into a chain of Laplace resonances, resulting in regular alignments as they orbit. This artist's animation shows the planets orbiting the stars, with musical notes playing for each planet as it completes a half orbit. When planets align at these points, a resonance is heard.
