planetary motion is the motion of planets across the sky . Johannes Kepler gave the 3 laws of planetary motion

In physics, an orbit is the gravitationally curved trajectory of an object around a point in space, for example the orbit of a planet about a star[1][2] or a natural satellite around a planet. Normally, orbit refers to a regularly repeating path around a body, although it may occasionally be used for a non-recurring trajectory around a point in space. To a close approximation, planets and satellites follow elliptic orbits, with the central mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion.

Current understanding of the mechanics of orbital motion is based on Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics. For ease of calculation, in most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse square law.[3]
