Orbital mechanics

A satellite orbiting the earth has a tangential velocity and an inward acceleration.

A Hohmann transfer from a low circular orbit to a higher circular orbitA bi-elliptic transfer from a low circular starting orbit (dark blue), to a higher circular orbit (red)Generic two-impulse elliptical transfer between two circular orbitsA general transfer from a low circular orbit to a higher circular orbitAn optimal sequence for transferring a satellite from a supersynchronous to a geosynchronous orbit using electric propulsion

Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and Newton's law of universal gravitation. It is a core discipline within space mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity, including both spacecraft and natural astronomical bodies such as star systems, planets, moons, and comets. Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary transfers, and is used by mission planners to predict the results of propulsive maneuvers. General relativity is a more exact theory than Newton's laws for calculating orbits, and is sometimes necessary for greater accuracy or in high-gravity situations (such as orbits close to the Sun).
