• Anomaly — A deviation from a norm, from a rule, or from natural laws of development; irregularity, strangeness, structural or functional non-conformity. In medicine, the term denotes a congenital malformation, anatomical asymmetry, or biological disruption present from birth. In astronomy, it represents a structural angle used to determine the exact position of a celestial body on its elliptical orbit relative to the periastron.
