- a deviation from the common rule, type, arrangement, or form.
- 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.
- an odd, peculiar, or strange condition, situation, quality, etc.
- an incongruity or inconsistency.
- a quantity measured in degrees, defining the position of an orbiting body with respect to the point at which it is nearest to or farthest from its primary.
- the amount of deviation of a meteorological quantity from the accepted normal value of that quantity.
- irregularity.
- something anomalous
- deviation from the normal or usual order, type, etc; irregularity
- astronomy
- the angle between a planet, the sun, and the previous perihelion of the planet
- 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
- the angle between the periapsis of an orbit and the position of an imaginary body orbiting at a constant angular speed and in the same period as the real orbiting body
- geology
- a deviation from the normal value of gravity at the earth's surface, caused by density differences at depth, for example those caused by a buried mineral body
- a magnetic field, for example one produced by a buried mineral body, that deviates from an expected or standard value, usually that of the earth's magnetic field
