Comparative Investigation of the Newtonian Gravitational Field and the Exact Gravitational Field — •Amboer Jiaer Li1 and Hans-Otto Carmesin1,2,3 — 1Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen — 2Studienseminar Stade, Bahnhofstr. 5, 21682 Stade — 3Gymnasium Athenaeum, Harsefelder Straße 40, 21680 Stade
Understanding gravitational fields is fundamental to celestial mechanics and space exploration. This project investigates the differences between the classical Newtonian gravitational field and the relativistic exact gravitational field (Carmesin 2024, 2025), using Mercury as a test case. The gravitational acceleration is computed for both models over varying distances, using Python. Preliminary findings aim to assess the validity of Newtonian gravity in practical applications and explore the necessity of relativistic corrections in scenarios requiring high accuracy. This research provides insights into the limitations of classical mechanics in planetary science and informs future computational approaches for interplanetary missions.
