The celestial orb which revolves round the earth; the satellite of the earth; a secondary planet, whose light, borrowed from the sun, is reflected to the earth, and serves to dispel the darkness of night. The diameter of the moon is 2,160 miles, its mean distance from the earth is 240,000 miles, and its mass is one eightieth that of the earth. See Lunar month, under Month.
A secondary planet, or satellite, revolving about any member of the solar system; as, the moons of Jupiter or Saturn.
The time occupied by the moon in making one revolution in her orbit; a month.

can be any natural object orbiting around another; often refers to the Moon of the Earth (but other planets have moons too.) The Moon of the Earth was probably formed when a large object struck the Earth a long time ago.
The large rocky body orbiting the Earth around every ~28 days.
(see also Satellite): A natural celestial body having a regular orbit around another larger body, such as a planet.
With a diameter of 3500 km, Earth's Moon is actually quite large for a moon. It orbits the Earth at a distance of 385,000 km. Since the same side of the moon always faces Earth, a Moon 'day' is 29.5 Earth days. It is thought that when the Earth formed it had no moon. Then, about 4.5 billion years ago a small planet hit Earth. The impact caused the Earth's surface to become molten, and the small planet became gravitationally bound to Earth, becoming the Moon. Although it can be confusing, the word moon is also used generically to mean any object which orbits another object. Check out SEDS' Nine Planets, for more about the Moon.

The Earth's satellite. The Moon is classed as a planet ("wanderer") in astrology and represents matters to do with women, the mother, the public, the emotions and so on. A feminine planet, she rules Cancer and is exalted in Taurus. Several other planets have recently been determined by astronomers to have moons, but these are not generally considered in astrology.
A planetary satellite. Moons are dense rocky bodies that orbit planets.

(1) The Earth's satellite, which orbits at a distance of 384 500 km. Its mass is one-eightieth (1/80) and its gravity one-sixth (1/6) of the Earth's. Surface temperatures range from 80-400 . It has no atmosphere. (2) General name also given to natural satellites, e.g., the moon of Jupiter and Saturn.
A smaller body orbiting a planet. Also referred to as a natural satellite.
The Moon is Earth's only natural satellite. It has no formal English name other than "the Moon", although it is occasionally called Luna (Latin for "moon") to distinguish it from the generic term "moon" (referring to any of the various natural satellites of other planets). Its symbol is a crescent .
In the fiction of J. R. R. Tolkien, the moon of Middle-earth was created by the Vala AulÃ«.
