The 15 pages that link to Orbital perturbation, each with the reason it gives.

• Kepler's laws of planetary motionRelated: Perturbations account for departures from perfectly Keplerian planetary paths.

• Orbital mechanicsRelated: Real trajectories depart from the ideal models that define the basic orbital framework.

• Orbital elementsRelated: Perturbations make real orbital elements change over time.

• Hohmann transfer orbitRelated: Perturbations can shift the endpoints and timing predicted by the ideal Hohmann model.

• Specific orbital energyRelated: Perturbations can make the two-body specific energy vary over time.

• OrbitRelated: Other bodies and non-gravitational forces make real trajectories depart from simple ideal orbits.

• Molniya orbitRelated: Earth’s gravity field changes the orientation of an uncorrected Molniya orbit.

• Geosynchronous orbitRelated: Lunar, solar, and Earth-shape effects gradually alter geosynchronous satellite orbits.

• Orbital station-keepingRelated: Perturbations create the drift that station-keeping maneuvers must counter.
