Orbital stability is a branch of celestial mechanics that deals with the long-term behavior of objects in space, particularly with regards to their orbits and gravitational interactions. This area of research seeks to understand the dynamics of celestial bodies and how they respond to changes in their orbits over time. Researchers in this field study the stability of various orbital configurations, including those of planets, moons, stars, and other celestial bodies, to determine the likelihood of catastrophic events such as collisions or ejections. Orbital stability research is important for predicting and preventing potential threats to Earth and other celestial bodies, as well as for understanding the formation and evolution of planetary systems.
