The library calculates positions of the Sun, Moon, and planets, and predicts astronomical events such as rise/set times, lunar phases, equinoxes, solstices, eclipses, and transits. It is based on the 'VSOP87' planetary model and is accurate to within approximately one arcminute. This package bundles the single-file C source so that other R packages can link against it via 'LinkingTo' without shipping their own copy. authors: - family-names: O'Hara-Wild given-names: Mitchell email: mail@mitchelloharawild.com orcid: https://orcid.org/0000-0001-6729-7695 - family-names: Cross given-names: Don repository: https://mitchelloharawild.r-universe.dev repository-code: https://github.com/mitchelloharawild/astronomyengine commit: 78a4e6fddd903a3a3caa973d3a473fdde4765f23 url: https://github.com/mitchelloharawild/astronomyengine date-released: '2026-03-02' contact: - family-names: O'Hara-Wild given-names: Mitchell email: mail@mitchelloharawild.com orcid: https://orcid.org/0000-0001-6729-7695
