Considering orbital mechanics, I would like to ask what would be the effect of nearby planets such as the Earth or Jupiter on a Dyson sphere. A Dyson sphere is not realistic because of the tremendous forces and instability of the structure. So maybe the same question could be asked for a Dyson swarm.

There is a related question What would keep Dyson Swarm reflectors in place? about the effect of the Sun's radiative pressure. Also a 2020 review article on Dyson spheres by Jason Wright provides insights into the question of optimal size of a Dyson sphere.
