Etymology
From Latin anomalia, from Ancient Greek ἀνωμαλία (anōmalía, “irregularity, anomaly”), from ἀνώμαλος (anṓmalos, “irregular, uneven”), negating the meaning of ὁμαλός (homalós, “even”), from ὁμός (homós, “same”).
Webster’s 1913
- noun Deviation from the common rule; an irregularity; anything anomalous.
- noun (a) 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. The mean anomaly is what the anomaly would be if the planet's angular motion were uniform.
