Research Artwork Course notes Associations Simulations 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
Luna moth common name became "Luna moth". Several other North American giant silk moths were also given species names after Roman or Greek mythology. The Luna moth is found in North America, from east of the Great Plains in the United States – Florida to Maine, and from Saskatchewan eastward through central Quebec to Nova Scotia in Canada. Based on the climate in which they live, Luna moths produce different numbers of generations per year. In Canada and northern regions of the United States they are univoltine, meaning one generation per year. Life stages are approximately two weeks as eggs, 6–7 weeks
