In astronomy, an anomaly is a quantity measured with respect to an apsis, usually the periapsisEccentric anomaly, an intermediate value used to compute the position of a celestial object as a function of timeFlyby anomaly, an unexpected energy increase during the flybys of the Earth by various satellitesMean anomaly, a measure of time in the study of orbital dynamicsPioneer anomaly, the observed deviation of the trajectories of some unmanned space probes, and especially Pioneer 10 and Pioneer 11South Atlantic Anomaly, the region in outer space where the Earth's inner van Allen radiation belt makes its closest approach to the surface of this planetTrue anomaly, the angle between the direction of periapsis and the current position of an object on its orbitAnomalous precession, another term for "apsidal precession"

Physics
Anomaly (physics), a failure of a symmetry of a theory's classical actionConformal anomaly, a quantum phenomenon that breaks the conformal symmetry of the classical theoryChiral anomaly, an anomalous nonconservation of a chiral currentGauge anomaly, the effect of quantum mechanics that invalidates the gauge symmetry of a quantum field theoryGlobal anomaly, an anomaly in quantum physicsGravitational anomaly, an effect in quantum mechanics that invalidates the general covariance of some theories of general relativityMixed anomaly, an effect in quantum mechanicsParity anomaly, an anomaly that is associated with parityKonishi anomaly, the violation of the conservation of the Noether current associated with certain transformationsAnomalons, some odd particle interactions that are seen in some high-energy physicsAnomalous skin effect, when electromagnetic fields penetrate into a metal by an amount comparable to, or much less than, the mean free path. Brian Pippard used it to determine the Fermi surface of copper.Anomalous dispersion (optics), when the speed of an electromagnetic wave increases with increasing frequency
