Webb12 nov. 2024 · However, recent observational and theoretical studies imply that 'Oumuamua is not an active comet. We explore the possibility that the excess acceleration results from solar radiation pressure. The required mass-to-area ratio is ( m / A ) ≈ 0.1 g cm −2. For a thin sheet this requires a thickness of ≈0.3–0.9 mm.
