All proposed gravitational explanations of the Pioneer anomaly must crucially face the Equivalence Principle. Thus, if Pioneers 10 and 11 were influenced by anomalous gravitational effects in regions containing other Solar System bodies, then those bodies should likewise be influenced, irrespective of their shape, composition or mass. Although the lack of any observed influence upon planetary orbits severely constrains such explanations, here we aim to construct by computer modeling… Expand

The Pioneer anomaly in covariant theory of gravitation
The difference of equations of motion in the covariant theory of gravitation and in the general theory of relativity is used to explain the Pioneer anomaly. Calculation shows that the velocities of...


Could the Pioneer anomaly have a gravitational origin
If the Pioneer anomaly has a gravitational origin, it would, according to the equivalence principle, distort the motions of the planets in the Solar System. Since no anomalous motion of the planetsExpand
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
Can Minor Planets Be Used to Assess Gravity in the Outer Solar System
The twin Pioneer spacecraft have been tracked for over 30 years as they headed out of the solar system. After passing 20 AU from the Sun, both exhibited a systematic error in their trajectories thatExpand
Can the Pioneer Anomaly be of Gravitational Origin? A Phenomenological Answer
In order to satisfy the equivalence principle, any non-conventional mechanism proposed to gravitationally explain the Pioneer anomaly, in the form in which it is presently known from the so-farExpand
Pioneer anomaly and the Kuiper Belt mass distribution
Pioneer 10 and 11 were the first probes sent to study the outer planets of the Solar System, and Pioneer 10 was the first spacecraft to leave the Solar System. Besides their already epic journeys,Expand

Testing Gravity in the Outer Solar System: Results from Trans-Neptunian Objects
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 unmodeledExpand

Abstract In this paper, we investigate the effects that an anomalous acceleration as that experienced by the Pioneer spacecraft after they passed the 20 AU threshold would induce on the orbitalExpand
