anomaly definition
anomaly, anomalousness(noun) deviation from the normal or common order or form or rule. anomaly, unusual person(noun) a person who is unusual. anomaly(noun) (astronomy) position of a planet as defined by its angular distance from its perihelion (as observed from the sun) Word of the day: manticore. a monster with a lion's body, a scorpion's tail, and a man's head with three rows of teeth. It roamed the jungles of India and, like the Sphinx , would ask travellers a riddle and kill them when they failed to answer it. See full definition. New on the Scrabble blog. Astronomy and celestial mechanics. 1  In astronomy, an anomaly of an elliptical orbit, generally measured with respect to an apsis, usually the periapsis. 2  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. What is an 'Anomaly'. An anomaly is a term describing the incidence when the actual result under a given set of assumptions is different from the expected result. An anomaly provides evidence that a given assumption or model does not hold in practice. The model can either be a relatively new or older model. noun, plural anomalies. 1. a deviation from the common rule, type, arrangement, or form. Synonyms: abnormality, exception, peculiarity. 2. an anomalous person or thing; one that is abnormal or does not fit in: With his quiet nature, he was an anomaly in his exuberant family. Synonyms: abnormality, exception, peculiarity.

Eccentric anomaly, an intermediate value used to compute the position of a celestial object as a function of time. Also called : eccentric anomaly. the angle between the periapsis of a particular point on a circle round the orbit as seen from the centre of the orbit. This point is obtained by producing a perpendicular to the major axis of the ellipse through the orbiting body until it reaches the circumference of the circle. Anomaly(noun) deviation from the common rule; an irregularity; anything anomalous. Anomaly(noun) the angular distance of a planet from its perihelion, as seen from the sun. This is the true anomaly. The eccentric anomaly is a corresponding angle at the center of the elliptic orbit of the planet.
