the anomalous acceleration of Oumuamua decreased as 1/r2 exactly as with numerous other comets due to radiation pressure & radiation-induced off-gassing.SLockhart said:But there's just no example in the literature of a comet giving off 'larger dust' without also giving off gases and water. The scientists are inventing 'natural' reasons in order to avoid even mentioning the dreaded A word. Unfortunately the soonest we could possibly reach it is 2036 so it seems likely to remain a mystery.
Is it impossible, that the object was actually very small, meteoroid in size... and that it was off-gassing, was producing a (small) coma, which is the only reason we observed it at all? a 1m object off-gassing reflects as much light and IR as the 100m object inferred from SPITZER ?? Especially if only one side of the object retained volatiles to off-gas ? Such that the coma dwindled down each time the snowy side swung into shadow ??
