Pax is asteroid #679 and also known as 1909 FY. Pax was discovered by August Kopff. The orbit of Pax is characterized by an inclination of 24.387°, an eccentricity of 0.31135, and a sidereal period of 1518.8 days.

Pax is named after the Roman goddess Pax, who is the goddess of peace and hence the Roman counterpart to the Greek goddess Eirene (Εἰρήνη). Pax was, different from the Greek goddess, first only the Latin word for peace. Then Pax became a political program of Gaius Octavius, better known as the emperor Augustus. The early Roman Empire had a long, peaceful time known as the Pax Augusta or Pax Romana. The political program involved establishing a cult around the new goddess Pax. During the Pax Romana she became a fully grown goddess with all characteristics of a Roman goddess, except a mythological tale. Pax had a festival held for her on January 3rd. In art she is commonly depicted holding out olive branches as a peace offering, as well as a caduceus, cornucopia, corn, and a sceptre. The Roman idea of peace wasn’t simply the absence of war, but the outcome of victory and the result of showing dominance and strength. Hence the Roman military author (of Epitoma Rei Militaris or De Re Militari) Publius Flavius Vegetius Renatus, known as Vegetius, explained later: “si vis pacem, para bellum”, which means “if you want peace, then prepare for war!”.

Because Pax is a result of strength, so the astrological force Pax shows strength. Of course also the result of being on guard. Only for synastries is Pax less suitable than Irene. If peace itself is the subject of astrological investigation, then all the peace deities, but also war deities, should be considered.
