Celestial mechanics Celestial mechanics Celestial mechanics is the branch of astronomy that deals with the motions of objects in outer space. Historically, celestial mechanics applies principles of physics (classical mechanics) to astronomical objects, such as stars and planets, to produce ephemeris data. As an astronomical field of study, celestial mechanics includes the sub-fields of orbital mechanics, which deals with the launching and orbits artificial satellites, and lunar theory, a specialty which deals with the complications of the orbit of the Moon. Modern celestial mechanics tends to divide between five broad fields of study: All of the above fields overlap, but are sometimes
Lord's New Church Which Is Nova Hierosolyma "De Hemelsche Leer" (The Celestial Doctrine), a Dutch periodical started by Pfeiffer in 1929. Emanuel Swedenborg, whose writings compose the distinctive body of material used by the General Church, had proposed the idea that the Bible had, in addition to its intended material meaning, a spiritual meaning that had been revealed through the communications between Swedenborg and the angelic realm.
