https://www.researchgate.net/publication/350617258_Gravitational_Fields_and_Gravitational_Waves Applying Newton's universal gravitational equation, we have been able to calculate the orbital data and orbital precession data of the planets in the solar system more accurately, but there are deviations between these data and astronomical observations. For example, the orbital precession of Mercury has a deviation of 43" per century. LIGO has discovered gravitational waves from the depths of the universe, confirming that gravitational waves are real, which brings us some new ideas for studying planetary orbits. We know that the disturbance of the gravitational field will cause gravitational waves, then the sun’s shuttle in the Milky Way will also cause disturbances to the gravitational field of the Milky Way, thus forming gravitational waves around the sun, although it is very weak. But because the planets in the solar system are not far from the sun, the planets will feel the influence of gravitational waves, which will affect the orbits of the planets. This article will analyze the specific distribution of gravitational waves around the sun, and derive the dynamic gravitational equation under the influence of gravitational waves, and apply it to the calculation of planetary orbits, and verify the correctness of the dynamic gravitational equation by comparing it with the astronomical observation data released by NASA. I'm back, and here's where I started.
