Thank you for supporting the creative commons movement !! Full Moon an important cultural influence object from antiquity both in language and in the calendar , art and mythology. The gravitational influence of the Full Moon causes the tides and increasing day length. The orbital distance of the Full Moon, about thirty times the diameter of Earth, makes it look in the sky with the same size as the Sun and the Full Moon can cover exactly the Sun in the solar eclipses total. The Full Moon is the first celestial body on which humans have performed a manned descent . Although the Full Moon program of the Soviet Union was the first to reach the Full Moon with a spaceship unmanned, the Apollo program of United States got the only manned missions to date, beginning with the first manned lunar orbit by the Apollo 8 in 1968 and six manned lunar landings between 1969 and 1972. Some planned future manned missions to the Full Moon, have not been launched yet. The Full Moon remains, under the Outer Space Treaty , free to explore any peaceful nation. The Full Moon is exceptionally large compared to the planet Earth: a quarter of the diameter of the planet and 1/81 its mass. It is the largest of the Solar System relative to the size of its planet-satellite. The surface of the Full Moon is less than a tenth of the Earth, which is about a quarter of the Earth's continental area. However, the Earth and Full Moon are still considered un-planet satellite system instead of a double planetary system, as their barycentre , which is located about 1700 km (about a quarter of the Earth's radius) beneath the surface of Earth. The general hypothesis today is that the Earth-Full Moon system formed as a result of an impact : a celestial body the size of Mars collided with the young Earth, flying material into orbit around it, which merged to form the Full Moon . In astronomy , a lunar distance (LD) is a measure of the distance from the Earth to the Full Moon. The average distance between Earth and the Full Moon is 384,400 kilometers. The actual distance varies along the orbit of the Full Moon . As the Full Moon takes the same time to circle in on itself around the Earth, it always presents the same face. This is because the Earth, an effect called gravitational gradient , completely stopping the Full Moon. Most regular satellites exhibit this phenomenon regarding their planets. So, until the time of the space research was not possible to see the hidden Full Moon face, having an asymmetry with respect to the face. The sun always illuminates half of the Full Moon, which does not coincide with the public face, producing the phases of the Full Moon . The apparent freezing of the Full Moon relative to Earth occurred because the Earth's gravity acts on the irregularities of the lunar globe so that over time the visible part is over 4 km radius not visible, the still center gravity Full Moon of the lunar center moved 1.8 km to Earth. The fact that the Full Moon rises about an hour later each day knowing explained the orbit of the Full Moon around the Earth. The Full Moon completes one revolution around the Earth in about 28 days approximately. If Earth did not rotate on its own axis, it would be very easy to detect the motion of the Full Moon in its orbit. This motion causes the Full Moon forward about 12 ° in the sky every day. If Earth did not rotate, which would be the Full Moon across the night sky from west to east for two weeks and then be absent two weeks (during which the Full Moon would be visible on the opposite side of the globe). However, the Earth completes one rotation every day (rotation direction is east). Thus, each day takes you to Earth about 50 minutes to be facing the Full Moon again (which means that you can se...
