moons

1. often Moon The natural satellite of Earth, visible by reflection of sunlight and having a slightly elliptical orbit, approximately 356,000 kilometers (221,600 miles) distant at perigee and 406,997 kilometers (252,950 miles) at apogee. Its mean diameter is 3,475 kilometers (2,160 miles), its mass approximately one eightieth that of Earth, and its average period of revolution around Earth 29 days 12 hours 44 minutes calculated with respect to the sun.

2. A natural satellite revolving around a planet.

3. The moon as it appears at a particular time in its cycle of phases: a gibbous moon.

4. A month, especially a lunar month.

5. A disk, globe, or crescent resembling the natural satellite of Earth.

6. Moonlight.

7. Something unreasonable or unattainable: They acted as if we were asking for the moon.

1. Often Moon. The natural satellite of Earth, visible by reflection of sunlight and traveling around Earth in a slightly elliptical orbit at an average distance of about 381,600 km (237,000 mi). The Moon's average diameter is 3,480 km (2,160 mi), and its mass is about ¹/₈₀ that of Earth. See more at giant impact theory.

2. A natural satellite revolving around a planet.

Our Living Language  : The Earth's Moon is a desolate and quiet place. The only natural satellite of Earth, it consists almost entirely of rock, shows no signs of ongoing geologic activity, has no water, and has a very thin atmosphere consisting primarily of sodium. But our Moon does not present a typical case for planetary satellites. Over the last 50 years, over a hundred more moons have been discovered in the solar system, so that they now total 138, nearly all of them orbiting the larger planets Jupiter, Saturn, and Uranus (Mercury, Venus, and Pluto have no moons, while Mars has two). Because they are so far from the Sun, these moons are for the most part extremely cold. Io, one of Jupiter's 63 known moons, is an exception. It is the most geologically active body in the solar system, with almost constant volcanic activity and a surface covered by cooling lava. Some scientists think that another moon of Jupiter, Europa, may have liquid water capable of supporting life underneath a thick layer of surface ice. Titan, one of Saturn's moons, may also be capable of supporting primitive life in the ocean of liquid methane on its frigid surface.
