The ejection of planetesimals into the Oort Cloud caused a gravitational effect on Uranus and Neptune, leading them to move further from the Sun. This is due to the conservation of angular momentum, where the planetesimals moving away from the Sun transferred their angular momentum to Uranus and Neptune, causing them to move further outwards in their orbits. The ejection of planetesimals from the outer solar system pushed Uranus and Neptune further out from the Sun. This is known as the "Nice model" of solar system formation.
