Anomalous Acceleration
Beginning in 2018, orbital observations revealed systematic deviations from predicted trajectories consistent with a non-gravitational force of approximately $$a = (4.92 \pm 0.04) \times 10^{-10} \text{ m/s}^2$$.[^7] This acceleration remains unexplained by conventional outgassing mechanisms and has prompted speculation regarding solar radiation pressure, residual cometary outgassing, or conversely, the presence of an accompanying exoplanet generati…
