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
Africa (goddess) "in Africa nemo destinat aliquid nisi praefatus Africam", which scholars translate as "no one in Africa does anything without first calling on Africa". This has been the literary proof of her existence and importance, in some cases interpreted as a proof for a North African goddess-centric cult.
