Chapter four covers the cause and geometry of the lunar phases and the conditions for solar and lunar eclipses. Use it to establish the physical, astronomical mechanics of a lunar phase or an eclipse; it is not a source on any tradition's religious or symbolic reading of these astronomical events, which needs a source specific to that tradition.FactsClaims Backed By This Source (175 claims)Comments (0)Reader Challenges (0 open reader challenges)FactsAssessmentReliability TierWell-attested1A peer-reviewed, open-access university astronomy textbook published through OpenStax at Rice University; its standing rests on that documented peer-review process and its use as an actual course textbook, checkable against the reviewed content itself.NotesWell-attestedPeer-reviewed open-access university astronomy textbook.
