'''Astrodynamics''' is the study of the motion of [[Rocket|rockets]], missiles, and space vehicles, as determined from Sir Isaac Newton's laws of motion and his law of universal gravitation. It is a specific and distinct branch of celestial mechanics, which focuses more broadly on Newtonian gravitation and includes the orbital motions of artificial and natural astronomical bodies such as [[Planet|planets]], moons, and comets. Astrodynamics is principally concerned with spacecraft trajectories, from launch to atmospheric re-entry, including all orbital maneuvers, orbit plane changes, and interplanetary transfers. | '''Astrodynamics''' is the study of the motion of [[Rocket|rockets]], missiles, and space vehicles, as determined from Sir Isaac Newton's laws of motion and his law of universal gravitation.
