IMCCE
The IMCCE (Institut de mécanique céleste et de calcul des Ephémérides - Institute of celestial mechanics and ephemeris calculations) is a research institute associated with the Observatoire de Paris and is a unité mixte de recherche of the National Research Centre CNRS (UMR 8028). It is also associated with the Pierre and Marie Curie university and the Lille 1 university.

Research topics
The IMCCE does research, teaching and provides services.
The research done at the IMCCE concerns celestial mechanics, the dynamics of bodies in the solar system, astronomy, planetological dynamics, hamiltonian dynamical systems, evolution of the solar system and other dynamical systems on long and short time scalesles, and their stability.
The work of the IMCCE covers a large spectrum combining theoretical studies with numerical analysis, astronomical observation, the development and "tuning up" of models, supplying data, calculating and publishing the ephemerides.
The work covers a vast set of solar system bodies: planets, natural satellites, small bodies, artificial satellites and space debris, as well as extrasolar systems.
This work also involves the development of theoretical or numerical tools for the study of dynamical systems (numerical integration, frequency analysis, orbit propagation ...), as well as the development and analysis of observations from the ground and in space, using various kinds of telescope (which can be small or very large).
Furthermore, the research involves the development of dynamical and physical models, and the analysis of observations: applications include tidal effects, the rotation of planets and their satellites, their geophysical aspects and internal structure, non-gravitational forces, collision risks etc. And finally, the purely theoretical aspects of the geometry of the N-body problem and celestial mechanics (non-interability, central configurations, bifurcations, diffusion ...) are being pursued.
In addition, the IMCCE provides certain services on a national level, and in particular makes available data and distributes the ephemerides. The Ephemeris Service (directed by Jérôme Berthier) guarantees the creation and distribution of the national ephemeris under the aegis of the Bureau des longitudes (BDL).
