What are the seven heavens Enoch travels through?

The sources note that Enoch describes seven heavens in some traditions, each with distinct inhabitants and purposes, yet they supply no further list or description of those seven realms or the sequence in which he travels through them (Place Facts - heaven).

What the texts do portray is Enoch's repeated ascent into layered celestial realms, where angelic guides lead him past storehouses of natural forces, prisons prepared for rebellious beings, and finally into the throne room itself. That chamber is marked by walls and floors of crystal together with streams of fire, a setting that unites beauty and danger while angels of named orders carry out their jurisdictions over nature and nations (Place Facts - heaven; Themes - Themes: Heavenly Journeys and Revelations).

His journeys also take him to the extremities of the earth, where he beholds open portals of heaven that release dew, rain, wind, cold, hail, and the courses of the stars; at each wonder he blesses the Lord of Glory who has wrought such works for angels, spirits, and humanity alike (Commentary - The Book of Enoch 36; Facts - The Book of Enoch 36; Commentary - The Book of Enoch 34). These visions establish him as the righteous scribe who records cosmic order and coming judgment, yet the precise identity of any seven heavens remains outside the detail given in the sources.
