| Abstract: | Evidence is presented indicating that the Flora family is of common origin. The distribution of proper elements and physical properties of Flora-family asteroids are compared with those of families believed to have formed from the catastrophic disruption of parent bodies. Differences in these orbital and physical properties suggest that the creation of the Flora family was more complex. Available evidence concerning the Flora family, together with recent models for the collisional evolution of the asteroids, suggests that this family may have originated from a binary or multiple asteroid. A mechanism in which the Flora family may have been produced by the disruption of a former major satellite of 8 Flora is presented and compared with other possible modes of formation. |
