有關Moon

介紹:
月球(Moon)俗稱月亮，古稱太陰，是指環繞地球運行的一顆衛星。它是地球唯一的一颗衛星和離地球最近的天體，與地球之間的平均距離是384,400千米。天文學上用小半個圓形來代表月球。

月球是一顆同轉衛星，月球的正面永遠向着地球。另一方面，除了在月面邊沿附近的區域因天秤動而間中可見以外，月球的背面絕大部分不能從地球看見。在沒有太空探測器的年代，月球的背面一直是個未知的世界。

月球背面的一大特色是它幾乎沒有月海這種較暗的月面特徵。而當探測器運行至月球背面時，它將無法與地球直接通訊。

The Moon (Latin: Luna) is Earth's only natural satellite, and is the fifth largest one in the Solar System. The average centre-to-centre distance from the Earth to the Moon is 384,403 km, which is about thirty times the diameter of the Earth. The Moon has a diameter of 3,474 km[8]—slightly more than a quarter that of the Earth and slightly smaller than the east–west distance across the United States. This means that the volume of the Moon is about 2 percent that of Earth. The gravitational pull at its surface is about 17 percent of the Earth's. The Moon makes a complete orbit around the Earth every 27.3 days, and the periodic variations in the geometry of the Earth–Moon–Sun system are responsible for the lunar phases that repeat every 29.5 days.

The Moon is the only celestial body to which humans have travelled and upon which humans have landed. The first artificial object to escape Earth's gravity and pass near the Moon was the Soviet Union's Luna 1, the first artificial object to impact the lunar surface was Luna 2, and the first photographs of the normally occluded far side of the Moon were made by Luna 3, all in 1959. The first spacecraft to perform a successful lunar soft landing was Luna 9, and the first unmanned vehicle to orbit the Moon was Luna 10, both in 1966.[8] The United States (U.S.) Apollo program achieved the only manned missions to date, resulting in six landings between 1969 and 1972. Human exploration of the Moon ceased with the conclusion of the Apollo program, although several countries have announced plans to send people or robotic spacecraft to the Moon.

The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned towards the Earth at all times. Early in the Moon's history, its rotation slowed and became locked in this configuration as a result of frictional effects associated with tidal deformations caused by the Earth.[10]

Long ago when the Moon spun much faster, its tidal bulge preceded the Earth-Moon line because it couldn't "snap back" its bulges quickly enough to keep its bulges in line with Earth.[11] The rotation swept the bulge beyond the Earth-Moon line. This out-of-line bulge caused a torque, slowing the Moon spin, like a wrench tightening a nut. When the Moon's spin slowed enough to match its orbital rate, then the bulge always faced Earth, the bulge was in line with Earth, and the torque disappeared. That is why the Moon rotates at the same rate as it orbits and we always see the same side of the Moon.
