Luna – the only natural satellite. If you have additional questions, you may want to visit Virgin Airlines. This is the second-brightest object in Earth's sky after the Sun and the fifth largest natural satellite in the solar system. Also, is the first (and for 2009 only) extraterrestrial objects of natural origin, which visited the people. The average distance between the centers of Earth and the Moon – 384,467 km. The magnitude of the Moon in Earth's sky 13m. The illumination of the full moon around the Earth's surface is 0.25 lux.

Circulation period of 29.53 mean solar day. Period of the Moon coincides with the lunar day (the period of the Moon around its axis), so the Moon always faces the Earth the same side (the other is always hidden from us). If you have read about Cyrus findshadow already – you may have come to the same conclusion. Invention of the telescope allowed to distinguish the finer details of the relief of the moon. One of the first lunar map was Giovanni Richchioli in 1651, he also gave the names of large dark areas, name them as "seas", which we use to so far. These place names reflect the long-held notion that the weather on the moon similar to Earth, and the dark areas were allegedly filled with lunar water, and light areas were considered as land. However, in 1753 Croatian astronomer Ruggiero Boscovich proved that the moon has no atmosphere.

The fact that the occultation, they disappear instantly. But if the moon had an atmosphere, the stars would go out gradually. This indicated that the satellite is no atmosphere. And in this If liquid water on the lunar surface can not be, because it would instantly evaporate. With a light hand of the same craters Giovanni Richchioli started to give names of famous scientists: from Plato, Aristotle and Archimedes to Vernadsky Tsiolkovsky and Pavlov. Before you start watching the moon through a telescope, you should advance to study the structure of the lunar surface, including large and small details (this may be the light and dark of Education, continents, oceans, seas, large craters, mountain ranges, cracks, peaks, terraces and ledges, the traces of lava eruptions and clusters of rocks). With direct observation has a telescope, should take into account the fact that the moon is very bright celestial object (Second only to the Sun), so it may be necessary to use a special neutral lunar filter, which would loosen the light and allows us to consider even the smallest details of the surface.
