Why do asteroids attract other asteroids?

Asteroids attract each other due to the force of gravity, which is proportional to their masses and inversely proportional to the square of the distance between them. When two asteroids come within a certain range, their gravitational pull can influence their trajectories, potentially leading to collisions or close encounters. Additionally, the accumulation of smaller particles can occur in regions where asteroids are present, further enhancing gravitational interactions. These interactions can lead to the formation of asteroid families or clusters over time.
