小行星在动态静止的圆盘中形成，但它们的轨道受到木星的引力搅动，足以导致高速碰撞。结果，数十颗大型小行星在太阳系的年龄范围内受到撞击的破坏，产生了被称为小行星家族的碎片群。在这里，我们解释了如何识别小行星家族，回顾其当前库存，并讨论如何利用它们来深入了解主带小行星的长期动态。行星数据系统节点上报告了 122 个著名家族成员的电子表格。
Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts over the age of the Solar System, producing groups of fragments known as asteroid families. Here we explain how the asteroid families are identified, review their current inventory, and discuss how they can be used to get insights into long-term dynamics of main belt asteroids. Electronic tables of the membership for 122 notable families are reported on the Planetary Data System node.
