Oral title: TRAPPIST: 10 years of Science and Operations in la Silla Oral abstract: TRAPPIST-South - for TRAnsiting Planets and PlanetesImals Small Telescope - is a 60 cm robotic telescope operated remotely by the Liège University in La Silla since June 2010. It is devoted exclusively to the study of planetary systems through two approaches: the detection and characterisation of exoplanets and the study of comets and other small bodies of the Solar System. We will review 10 years of operations and the main science results, showing that relatively small and dedicated telescopes can still play an important rôle, especially from excellent observing sites like la Silla.
