👉 "Subhalid" is a term used in celestial mechanics to describe a hypothetical object that orbits another celestial body in such a way that it does not enter into direct collision with the other body, but instead enters an orbit around it. This concept was first proposed by Johannes Kepler and has since been widely accepted as a fundamental principle of astrophysics, particularly in the study of planets and asteroids. The term "subhalid" is often used to describe objects that are not directly affected by collisions
