摘要

"Earth Moon system - the sun in order to study the fenu00c8menos natural.Utility model patent for a system to study natural phenomena involving the sun, earth and moon understood by the ball 57 which rotates freely.Positioned by bolts 66 and 67 on the shaft 60 fixed on shaft 23 and 15 attached to the separator 2, leaving the entire plan described above rotate freely, allowing to study the solstices.The equinoxes, seasons of the year, maximum declination of the sun, the tropics and polar circles because days and nights change its duration throughout the year and in different parts of the globe and the rod big 34.In the shape of a circular arc, which is freely attached to the flat separator 2, which house the screws 40 and 41.Where you can fit in the cylinder 48, which contains the cylindrical rod 52 and the ball less 56 which rotate freely, combining the movements of the rod big 34.The cylindrical rod 52 and the sphere smaller 56 can demonstrate the nodes ascendants and descendants and downgrading, the phases of the moon, why always the same face of the moon is directed toward the earth.Because the eclipses are repeated in 18.61 years and also the change of the route of the orbit of the moon.
