What prevents Vesta from growing larger in size?

Vesta, one of the largest asteroids in the asteroid belt, is significantly influenced by the gravitational force exerted by Jupiter. As a massive planet, Jupiter's gravity has a strong impact on the surrounding region of the solar system, including the asteroid belt where Vesta resides. During the early formation of the solar system, Jupiter's gravity likely disrupted the accretion of material in the asteroid belt, preventing Vesta and other bodies from accumulating enough mass to become larger planetesimals or even protoplanets.

Jupiter's gravity causes perturbations and can lead to collisions between smaller bodies in the belt or can eject them from the region entirely. This gravitational influence keeps Vesta in its current size and prevents it from gathering more material, as the dynamic environment created by Jupiter limits the ability of smaller objects to coalesce into larger ones. Understanding the impact of Jupiter's gravity on Vesta highlights the importance of planetary interactions in the formation and evolution of celestial bodies in our solar system.
