In a distant star system — a mere 1,300 light years away from Earth — researchers may have identified the first known planet to orbit three stars. Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems consist of two or more stars that are gravitationally bound to each other. But no planet orbiting three stars — a circumptriple orbit — has ever been discovered before. This has significant implications for bolstering our understanding of planet formation.
