# Relativistic Orbits

Relativistic orbits, a cornerstone of Einstein's theory of general relativity, elucidate the behavior of celestial bodies in gravitational fields. These orbits deviate from classical predictions, manifesting intriguing phenomena such as frame dragging and gravitational time dilation. Understanding relativistic orbits is paramount in diverse fields, from astrophysics to satellite navigation, where precision is essential. By accounting for the curvature of spacetime, relativistic models offer nuanced insights into the dynamics of orbiting bodies, challenging conventional Newtonian mechanics. This essay delves into the intricacies of relativistic orbits, exploring their implications across scientific disciplines and their role in shaping our understanding of the cosmos.
