Abstract
Transneptunian objects (TNOs) are small fossils of the Solar System orbiting beyond Neptune. We use stellar occultations to derive their size and shape. This work summarizes the main results derived, so far, from all detected TNO occultations (excluding Pluto system). We have developed a process, constructing astrometric star catalogues to make long-term reliable predictions (Camargo et al. 2014). Information about their physical properties are invaluable to the understanding of the dynamical evolution of the Solar System.
