Tests of general relativity - Wikipedia
网页Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
Einstein’s general relativity reveals new quirk of Mercury orbit ...
网页2018年4月11日 · Mercury orbits the sun in an ellipse that gradually rotates over time (illustrated). General relativity alters the predicted amount of rotation, which explains why Mercury’s orbit didn’t quite...

网页Perihelion of Mercury’s Orbit. A third prediction from Einstein’s theory of general relativity is the excess preces-sion of the perihelion of the orbit of Mercury of about 0.01° per century. This effect had been known and unexplained for some time, so in some sense its correct expla-nation represented an immediate success of the theory.
Why Newton’s Theory Couldn’t Explain Mercury’s Perihelion …
网页2023年7月28日 · The enigma of Mercury’s perihelion has perplexed astronomers and physicists for a considerable span of time. It revolves around the intriguing discrepancy that arises between the predicted and...
网页spacecraft in orbit about Mercury to estimate the precession of Mercury’s perihelion. We show that the MESSENGER ranging data allow us to measure not only the secular precession rate of Mercury’s perihelion with substantially improved accuracy, but also the periodic perturbation in the argument of perihelion sensitive to β and γ.
Precession of the perihelion of Mercury - Lawrence Berkeley …
网页An early success of Einstein's theory was an explanation for the 43'' per century precession of the perihelion of Mercury. In a curved spacetime a planet does not orbit the Sun in a static elliptical orbit, as in Newton's theory. Rather, the orbit is obliged to precess because of the curvature of spacetime.
Perihelion: What is it and when does it occur? | Space
网页2024年1月4日 · Mercury, the closest planet to the sun, has the most eccentric orbit, with the difference between the distance at perihelion and aphelion being 0.17 AU. That is quite a lot for Mercury, which...
Precession of Mercury's Perihelion from Ranging to the
网页2017年2月21日 · The perihelion of Mercury's orbit precesses due to perturbations from other solar system bodies, solar quadrupole moment (J 2), and relativistic gravitational effects that are proportional to linear combinations of the parametrized post-Newtonian parameters β and γ.
Numerical Analysis of Mercury’s Perihelion Shift
网页2023年7月6日 · In the current astrophysical community, it is generally accepted that the additional relativistic perihelion shift (advance) of Mercury is the difference between its observed perihelion shift and the one predicted by the N -body problem, and that this difference equals 43 ′′ per century.
