the color distribution of Trans-Neptunian Objects and what the very wide could provide with its three colors survey
A. Doressoundiram

The very wide survey will provide for a large sample of Trans-Neptunian Objects (TNOs) photometry in three bands with a high accuracy. this photometric accuracy is required to accomplish the spectral classification. Indeed, the differences between the known asteroids, types (which to first order look like the Sun) are much more subtle than stellar , types, so considerably higher photometric accuracy is necessary. , The more limited the range of wavelengths, the higher the accuracy needed to , distinguish asteroids of different types., , Information on the color distribution of TNOs is of high interest as it provides unique clues for the formation and evolution processes of these primitive bodies In turn, TNOs can help in understanding the formation of the outer solar system as well as other planetary systems. , , In this paper, I will review the current knowledge of the color properties of TNOs and describe the observed color distribution and trends within the Kuiper belt.
