hetegony (uncountable)

The study of the origin of the planets in the solar system.
- 1972, Robert Duncan Enzmann, Third Conference on Planetology and Space Mission Planning:
  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.
