hetegony (uncountable)

  1. The study of the origin of the planets in the solar system.
    • Because the origin of the solar system is essentially a question of the repeated formation of secondary bodies around a primary body, the term hetegony (from Greek hetairos or hetes, companion) has been suggested.1972, Robert Duncan Enzmann, Third Conference on Planetology and Space Mission Planning
