A planetary system of six exoplanets in near-perfect synchronization gives astronomers a hint at how such groupings could evolve. Over a period of seven years, astronomers have observed the star HD 158259 — invisible to the naked eye — discovering six planets in orbit around it in near-perfect synchronization. The extrasolar planets (exoplanets) consist of one ‘Super-Earth’ and five ‘Mini-Neptunes’ with exceptionally regular spacing and timing. Their regimented order gives researchers a hint as to how the system may have formed. The study, led by researchers from the University of Geneva (UNIGE), was conducted with the aid of the SOPHIE…
