| Outline of Research at the Start |
The size frequency distribution (SFD) of the planetesimals is a key for understanding their formation and growth process but is yet largely unknown. The Main Belt in our Solar System is the only viable observation target to estimate the SFD. In order to extract information on the original SFD of asteroid belt from the currently observed SFD, we build a comprehensive rotational and orbital model of main belt asteroids for asteroid family identification and validate with spectral data obtained with recent telescopic observation using our own space weathering experiments on meteoritic samples.
