planets move, so that there is no rubbing
All points at noon on planet Jupiter's equator move, with respect to the sun, Vo-Vr , at 2 km/sec. and photons , when leaving the sun's surface, move in the Sun's prograde rotation direction at 2 km/sec. If they retain that component during the ~45 minute journey, these 2 velocities match, so,
Solar ration energy there, and there only, goes straight down the hatch.
so to speak.
if that difference between the midday match absorption and everywhere else affects the fluids, their patterns on Jupiter, Saturn, the (Vo:Vr) x R relationship would be the base for an alternative theory.
The Sun has a way of dominating the "gravity versus centrifugal force" balance too, if you only move at 2 km/sec but if should be doing 13. to keep your constant distance. it could give you the sinking feeling. Or climbing if you are on Jupiter at noon or midnight. a fluid situation.
