The inverse square law of gravity is poorly probed by experimental tests at distances of ~10 AU. Recent analysis of the trajectory of the Pioneer 10 and 11 spacecraft have shown an unmodeled acceleration directed toward the Sun, which was not explained by any obvious spacecraft systematics, and occurred when at distances greater than 20 AU from the Sun. If this acceleration represents a departure from Newtonian gravity or is indicative of an additional mass distribution in the outer solar… Expand

Does the Neptunian system of satellites challenge a gravitational origin for the Pioneer anomaly
If the Pioneer anomaly (PA) was a genuine dynamical effect of gravitational origin, it should also affect the orbital motions of the Solar system's bodies moving in the space regions in which the PAExpand

Apsidal precession of the outer solar planetary orbits due to the pioneer anomaly
Abstract Despite the now common position that the Pioneer anomaly is not a real gravitational effect but an effect due to the on-board thermal recoil forces – for curiosity’s sake, we here take theExpand
