The Trappist-1 system is a planet system where the first exoplanets were discovered in 2015 with the Belgian telescope called TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) to which it gave its name. This is a good example of a system relatively different from ours and therefore offering a wealth of information.
Once you have watched this video, you will be able to discuss the differences between the Trappist-1 system and the Solar System.
