Effects on the solar system
he is always disrupting asteroids of the asteroid belt the reason why is because of his intense gravity, his magnetic field covers all of the solar system
 * he would crash them into him or other objects, killing them
 * he would steal them and capture them as his moons
 * he would eject them out

Planet collision theory
4541 million years ago, when he was a baby, a planet called Planet V once existed, Planet V was about the size of Uranus or Neptune, but then he came too close to Jupiter, and then he collided with him, this led to changes in the core and caused Jupiter to bleed, he then rapidly migrated inwards and push the rest of the gas planets' orbits outwards, and then he ate most of the gas in the inner ring, which explains why Mercury, Venus, Earth, and Mars are small.

4473 million years ago, an ice giant named Hades once existed in the system, but then she got too close to Saturn, and then Jupiter kicked her out of the system. causing Jupiter and Saturn's orbits to jump, during this, many of his irregular moons got captured by him.
