1. something anomalous

2. deviation from the normal or usual order, type, etc; irregularity

3. (Astronomy) deviation from the normal or usual order, type, etc; irregularity

4. (Astronomy) astronomy

a. Also called: true anomaly the angle between a planet, the sun, and the previous perihelion of the planet

b. 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

c. Also called: mean anomaly 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

5. (Geological Science) geology

a. Also called: gravity anomaly 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

b. Also called: magnetic anomaly 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
