Abstract: Trans-Neptunian Objects (or Edgeworth-Kuiper Belt Objects) and Centaurs are very faint and elusive objects, and a careful data reduction has to be performed. Growthcurve correction is the most common technique applied in order to optimise data extraction. At Paris-Meudon Observatory a multicolour photometric survey is being dedicated to these objects which might contain important clues on the formation of the Solar System. A large colour diversity is shown raising questions on their nature, formation processes and physical and chemical evolution. Some results of this survey are presented and discussed.
