. The Moon is the only natural companion of the Earth.
. The Moon is the only natural companion of the Earth. The Moon as a generic name denotes the celestial body that circles a star or planet. Moon distance to Earth is not constant, averaging 384,400 km. The Moon moves around the Earth along a slightly elliptical orbit. It circles the Earth in about 28 days (more precisely in 27 days, 7 hours and 43 minutes). The Moon is the Earth's closest celestial body, it is only 4 times less than the Earth, so the Earth-Moon system is also called double plan.
. The diameter of the Moon is 3,475 km, surface temperature (° C) : -170 to +130.
. Neil Armstrong and Bas Oldrins became the first people to descend on the Moon in 1969.
. There is no water vapor, air, wind, precipitation on the Moon, nor is the Moon atmospheric because its gravitational force is too small to hold gas molecules. Because there is no atmosphere on the Moon, it is an unsuitable environment for people to live in. There is no imaginable life on the Moon without the bumps, because the human body is not suitable for living without atmospheric pressure and with high temperature changes.
