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…

Constraints on the original ejection velocity fields of asteroid families
Asteroid families form as a result of large-scale collisions among main belt asteroids. The orbital distribution of fragments after a family-forming impact could inform us about their ejection

The two and three body mean motion resonances with Jupiter and Mars (and possible with Earth) may have significant effect on dynamics of very young close asteroids pairs and families. The most known

Asteroids are the remnants of planet formation, and as such, they represent a record of the physical and chemical conditions in the early solar system and its evolution over the past 4.6 billion

Asteroid families
An asteroid family is a group of asteroids with similar orbits and spectra that was produced by a collisional breakup of a large parent body. To identify asteroid families, researchers look for
The Breakup of a Main-Belt Asteroid 450 Thousand Years Ago
TLDR
This work takes advantage of a method for identification of recent breakups in the asteroid belt using catalogs of osculating (i.e., instantaneous) asteroid orbits and reports the discovery of a very young asteroid family around the object 1270 Datura.
The Effect of Yarkovsky Thermal Forces on the Dynamical Evolution of Asteroids and Meteoroids
The Yarkovsky effect is a thermal radiation force that causes objects to undergo semimajor axis drift and spinup/spindown as a function of their spin, orbit, and material properties. This mechanism
Evidence from the asteroid belt for a violent past evolution of Jupiter's orbit
We use the current orbital structure of large (>50 km) asteroids in the main asteroid belt to constrain the evolution of the giant planets when they migrated from their primordial orbits to their

A late Miocene dust shower from the break-up of an asteroid in the main belt
TLDR
It is reported that collisional disruption of the >150-km-diameter asteroid that created the Veritas family 8.3 ± 0.5 Myr ago also produced a transient increase in the flux of interplanetary dust-derived 3He, which reached a maximum of ∼4 times pre-event levels, and dissipated over ∼1.5″Myr.
