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
The Goddess of Spring Goddess of Spring" was among the first string of short films in which they used human characters. It provided much-needed experience for the upcoming major motion picture that Disney was designing. According to film historians, the animation skill level between "The Goddess of Spring" and "Snow White and the Seven Dwarfs" appears to have a twenty-year gap between the two; comparatively, it was only three years. The development in that span of time was monumental and is reflected in the major motion picture. Although feature-length cartoons were initially disregarded, the animation advancements attributed to "The Goddess of Spring", as they
