In this paper we first calculate the post-Newtonian gravitoelectric secular rate of the mean anomaly of a test particle freely orbiting a spherically symmetric central mass. Then, we propose a novel approach to suitably combine the presently available planetary ranging data to Mercury, Venus and Mars in order to determine, simultaneously and independently of each other, the Sun's quadrupole mass moment J2� and the secular advances of the perihelion and the mean anomaly. This would also allow to… Expand

Solar oblateness and Mercury's perihelion precession
The Keplerian laws of planetary motion are solutions of the two-body gravitational problem. Solar oblateness resulting from the rotation of the Sun distorts the gravitational force acting on a planetExpand

The post-Newtonian mean anomaly advance as further post-Keplerian parameter in pulsar binary systems
Abstract The post-Newtonian gravitoelectric secular rate of the mean anomaly ℳ is worked out for a two-body system in the framework of the General Theory of Relativity. The possibility of using suchExpand
History of solar oblateness measurements and interpretation
The story of the solar oblateness begins in the pre-relativity days when an explanation of the observed advance of Mercury’s perihelion was searched for. Then, examination of historical recordsExpand

Preliminary limits on deviation from the inverse-square law of gravity in the solar system: a power-law parameterization
New physics beyond the standard model of particles might cause a de- viation from the inverse-square law of gravity. In some theories, it is parameterized by a power-law correction to the NewtonianExpand

Is it possible to measure the Lense-Thirring effect on the orbits of the planets in the gravitational field of the Sun?
In this paper we explore a novel approach to try to measure the post-Newtonian 1/c 2 Lense-Thirring secular effect induced by the gravitomagnetic field of the Sun on planetary orbital motion. Due toExpand
Measuring the relativistic perigee advance with satellite laser ranging
The pericentric advance of a test body by a central mass is one of the classical tests of general relativity. Today, this effect is measured with radar ranging by the perihelion shift of Mercury andExpand

A confirmation of the general relativistic prediction of the Lense–Thirring effect
A measurement of the Lense–Thirring effect on two Earth satellites is reported: it is 99 ± 5 per cent of the value predicted by general relativity; the uncertainty of this measurement includes all known random and systematic errors, but the total ± 10 per cent uncertainty is allowed to include underestimated and unknown sources of error.

A test of general relativity using radio links with the Cassini spacecraft
A measurement of the frequency shift of radio photons to and from the Cassini spacecraft as they passed near the Sun agrees with the predictions of standard general relativity with a sensitivity that approaches the level at which, theoretically, deviations are expected in some cosmological models.
