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

• Two-body problemRelated: Third-body attractions and nonspherical masses perturb otherwise Keplerian motion.

• Orbit determinationRelated: Perturbations matter when a simple Keplerian model cannot match precise observations.

• Transit timing variationRelated: A companion’s perturbation changes the orbit and therefore the timing of successive transits.

• Long-period cometRelated: Passing stars and the Galactic tide can alter distant comet orbits.

• Orbital precessionRelated: Perturbing bodies can steadily rotate an orbit’s apsides or plane.

• Stellar orbitRelated: Other stars, planets, or a galaxy can alter a star’s nominal orbit.

• Rings of NeptuneRelated: Nearby moons perturb ring particles and influence their distribution.

• Hills cloudRelated: Perturbations are the proposed means by which cloud comets migrate into observable orbits.

• Nibiru cataclysmRelated: A massive nearby Nibiru would measurably disturb the orbits of planets and spacecraft.

• Planets beyond NeptuneRelated: A hidden planet could be inferred from persistent perturbations in smaller bodies’ orbits.
