Since Pluto was downgraded to a dwarf planet, astronomers have been fascinated more than ever by objects on the outskirts of our Solar System. The study of these objects with such intriguing names – Eris, Sedna, Haumea and many more – suggests that there may be a new planet hiding beyond the Kuiper belt. In this multimedia show, adapted by the Planétarium Rio Tinto Alcan team, we follow astrophysics professor Mike Brown and his team of fellow astronomers as they search for this ninth planet!
The planetarium team consulted researchers from the Institut de recherche sur les exoplanètes (iREx) at the Université de Montréal to validate different scenarios in order to introduce other points of view, bringing additional perspectives to this debated topic. After the show, audience members will have the opportunity to chat with science educators about the different viewpoints presented by experts.
