Asteroids, Comets, Meteors and Ephemerides

logo ACME


The team activities are centered on the dynamic and physical study of the small bodies of the Solar system (asteroids, comets and meteoroids). The goal is to better understand the step of the planetary formation by using the information on the young Solar system still present in the population of the small bodies. In consequence, we study the dynamic (orbits) of these bodies as well as the physical characteristics (size, 3-D shape, mass etc...) in order to understand their composition, their origin and to predict their future (ephemerids).


The team activities concern the different kinds of Solar system small bodies:

  • Asteroids:
    • Dynamic of the natural satellites of asteroids
    • Origin,mineralogy and physical characterization of asteroids
    • Modelization of the binary asteroids in contact
  • Comets
  • Meteors:
    • The FRIPON project
    • The CABERNET network
  • Artifical satellites

Observation devices

The team has in particular its own observation devices:

  • The planetology station of Pic du Midi
  • The 60 cm telescope of Réunion Island
  • The spectrometer SOVAG developed by the team
  • The FRIPON network
