In pheesics, an orbit is the gravitationally curved path o an object aroond a pynt in space, for ensaumple the orbit o a planet aroond the centre o a starn seestem, sic as the Solar Seestem.[1][2] Orbits o planets are teepically elliptical.

Current unnerstandin o the mechanics o orbital motion is based on Albert Einstein's general theory o relativity, which accoonts for gravity as due tae curvature o space-time, wi orbits follaein geodesics. For ease o calculation, relativity is commonly approximatit bi the force-based theory o universal gravitation based on Kepler's laws o planetary motion.[3]
