For planetary orbits, perturbations from radiation pressure while the sun is on the main sequence will be so small as to be negligible. Small perturbations may matter over billions of years, but perhaps more billions than the sun has life. Small bodies which are not in hydrostatic equilibrium (i.e., not massive enough to be round through…</p><p><a href="https://hackerpaper.kaipfister.de/p/1708.05513/">Paper and discussion history</a>.
