Anomaly

Anomaly may refer to:

Astronomy and celestial mechanics

In astronomy, an anomaly of an elliptical orbit, generally measured with respect to an apsis, usually the periapsis
Eccentric anomaly, an intermediate value used to compute the position of a celestial object as a function of time
Flyby anomaly, an unexpected energy increase during the flybys of the Earth by various satellites
Mean anomaly, a measure of time in the study of orbital dynamics
Pioneer anomaly, the observed deviation of the trajectories of some unmanned space probes, and especially Pioneer 10 and Pioneer 11
South Atlantic Anomaly, an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface
True anomaly, the angle between the direction of periapsis and the current position of an object on its orbit
Anomalous precession, another term for "apsidal precession"

Bouguer anomaly, anomaly in gravimetry
Free-air anomaly, gravity anomaly that has been computed for latitude and corrected for elevation of the station
Gravity anomaly, difference between the observed gravity and a value predicted from a model
