(MENAFN- Swissinfo) A Swiss-designed telescope travelling on board the CHEOPS space satellite has revealed three previously undiscovered planets orbiting a distant star, whose physical composition raises questions about how planetary systems are formed.

Previous observations of the TOI-178 star had pointed towards a three-planet system. CHEOPS soon found two other planets, with all five orbiting the star over different time spans (two, three, six, ten and 20 days) but in harmony with each other.
Scientists believed that yet another planet could be present with an orbit period of 15 days. The CHEOPS telescope evaded a near collision with space debris to confirm the hypothesis and reveal a sixth planet.
