A moon is a body which orbits a planet.
The Earth's Moon (sometimes known as "Luna") is a natural satelliteorbiting . Earth at an average distance of about 238,000 miles ( 380,000 km ). The Moon is unique in the solar system in its large relative size compared
. with the Earth.
The Moon appears from the Earth to be the same size as the sun,
. in perfect artistic symmetry, unlike any known other planet-moon system. Moreover, unlike most planets in the solar system, Earthhas only one moon.
And the Moon has two more remarkable artistic attributes:
. (1) it rotates and revolves in a way such
. that only one side is ever visible to the Earth and
. (2) its side that faces the Earth is smooth,
. while the side that remains hidden is jagged.
To those on Earth the Moon appears as an artistic disc
. that goes through phases in which greater or
. lesser amounts of the side lit by the sun are visible from Earth. Atheistshave proposed a number of theories to explain the Origin of the Moon,
. including a second planet colliding with Earth
. or even a second moon colliding with the first.
None of these theories are plausible and all lack evidential support.
A collision cannot plausibly explain why the Moon's smooth side faces
. the Earth while the jagged side is hidden from human view.
. 而鋸齒的一側是從人類的觀點隱藏。Source(s): S.H. Chen 系統工程師的居酒屋

The Moon is Earth's only known natural satellite,[nb 4] and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary, having a quarter the diameter of Earth and 1⁄81 its mass.[nb 5] The Moon is the second densest satellite after Io, a satellite of Jupiter. It is in synchronous rotation with Earth, always showing the same face; the near side is marked with dark volcanic maria among the bright ancient crustal highlands and prominent impact craters. It is the brightest object in the sky after the Sun, although its surface is actually very dark, with a similar reflectance to coal. Its prominence in the sky and its regular cycle of phases have since ancient times made the Moon an important cultural influence on language, calendars, art and mythology. The Moon's gravitational influence produces the ocean tides and the minute lengthening of the day. The Moon's current orbital distance, about thirty times the diameter of the Earth, causes it to appear almost the same size in the sky as the Sun, allowing it to cover the Sun nearly precisely in total solar eclipses.
