IAU Focus Meeting FM1:
A Century of Asteroid Families

August 28 – 29, 2018


Scientific Rationale:

The IAU 2018 GA occurs during the 100th anniversary of the identification of asteroid families by Kiyotsugu Hirayama. In this Focus Meeting, we will celebrate a century of asteroid family research, bringing together researchers from around the globe to review the history of the field, highlight major turning points in our understanding of asteroid families, present new results from recent asteroid family studies, and discuss the potential new avenues of research that will be opened in the coming years. Our 100th anniversary celebration will provide an excellent opportunity to showcase the worldwide research into asteroid families and excite the next generation of researchers who will begin the second century of family studies.
