A small change in a physical system, such as a variation in a planet's orbit resulting from the gravitational influence of other celestial bodies.
Variation in a designated orbit, as of a planet, that results from the influence of one or more external bodies. Gravitational attraction between planets can cause perturbations and cause a planet to deviate from its expected orbit. Perturbations in Neptune's orbit led to the discovery of the object—Pluto—that was causing the perturbation. Perturbations in the orbits of stars have led to the discovery of planetary systems outside of our Solar system.
