Solar radiation pressure on a natural body with a very low mass-to-area ratio, such as a fractal dust aggregate.
Where it stands
Still possibleIts tests haven't settled it: two pieces of evidence for, one against. It needs two reviews to be accepted.
What it predicts
- The bulk density is around 10^-5 g per cubic centimetre (or the body is a very thin natural sheet).
- The acceleration falls off exactly as the inverse square of distance and has no component that varies with spin phase beyond geometry.
- The thermal infrared behaviour differs from a solid body's in ways future observations can measure.
What would rule it out
- An infrared detection of a future analogue whose thermal behaviour matches a solid body, or proof that no natural process makes such aggregates at this size.
