  Moon - Wikipedia, the free encyclopedia
The plane of the lunar orbit maintains an inclination of 5.145 396° with respect to the ecliptic (the orbital plane of the Earth), and the lunar axis of rotation maintains an inclination of 1.5424° with respect to the normal to that same plane.
The points where the Moon's orbit crosses the ecliptic are called the "lunar nodes": the North (or ascending) node is where the Moon crosses to the North of the ecliptic; the South (or descending) node where it crosses to the South.
Lunar Prospector results, however, indicate the presence of hydrogen in the permanently shadowed regions, which could be in the form of water ice.

 Lunar eclipse - Wikipedia, the free encyclopedia
The type and length of a lunar eclipse depends upon the Moon's location relative to its orbital node.
If you were on the Moon's surface during a lunar eclipse you would witness a solar eclipse, with the Earth passing in front of the Sun.
Ancient Greek astronomers noticed that during lunar eclipses the edge of the shadow was always circular; they thus concluded that the Earth was spherical.

 Lunar Regolith Breccias   (Site not responding. Last check: 2007-10-06)
Lunar regolith is composed in part of rock and mineral fragments that were broken apart from underlying bedrock by the impact of meteorites.
Rock and mineral fragments at the lunar surface are exposed to the solar wind — ions of mostly-light elements like hydrogen and helium that are emitted from the sun at exceedingly high speeds, several hundred kilometers per second.
Because the Moon is closer to the sun than the asteroids and because the lunar regolith is thicker than those of asteroids, lunar regolith breccias are much richer in solar-wind implanted gases than are asteroidal regolith breccias.

 Lunar Meteorites   (Site not responding. Last check: 2007-10-06)
A weathered lunar meteorite would not be an impressive or suspicious looking rock if found in a cornfield or streambed (see Dar al Gani 400 or QUE94281) and a brecciated lunar meteorite could easily be overlooked in the field as a terrestrial sedimentary rock.
Lunar meteorites that are mare basalts (e.g., NWA 032) or breccias composed mainly of mare material (EET 87521/96008) are poor in aluminum and rich in iron.
Lunar Prospector mission (1998—99) have shown that all of the Apollo sites were in or near a unique and anomalously radioactive “hot spot” on the lunar nearside in the vicinity of Mare Imbrium.

 Surface Properties of the Moon
One of the discoveries of the first Lunar orbiters is that the far side has a very different appearance than the near side.
The bulk density of the Moon is 3.4 g/cc, which is comparable to that of (volcanic) basaltic lavas on the Earth (however, the bulk density of the Earth is 5.5 g/cc, because of the dense iron/nickel core).
The Anorthosites that are common in the Lunar Highlands are not common on the surface of the Earth (The Adirondack Mountains and the Canadian Shield are exceptions).

 Lunar Perigee and Apogee Calculator
Perigee and apogee distances are usually accurate to within a few kilometres compared to values calculated with the definitive ELP 2000-82 theory of the lunar orbit; the maximum error over the years 1977 through 2022 is 12 km in perigee distance and 6 km at apogee.
ELP 2000-85 generates predictions of lunar longitude accurate to 0.0004 degrees for the years 1900 through 2100, and 0.0054 degrees for the period 1500 through 2500.
Machine-readable files for all of the tables and a sample FORTRAN program which uses them to compute lunar ephemerides may be obtained from the Astronomical Data Center at the NASA Goddard Space Flight Center by FTP across the Internet, or on CD-ROM, along with a wide variety of other astronomical catalogues and tables.

 full moon and lunar effects
Lunar effects that have been found have little or nothing to do with human behavior, e.g., the discovery of a slight effect of the moon on global temperature,* which in turn might have an effect on the growth of plants.
Anecdotal evidence for lunar effects is not hard to find and reporters know that one good anecdote trumps ten scientific studies when it comes to reader interest, even though such evidence is unreliable for establishing significant correlations.
According to Nienhuys, the 161 figure refers to the average number of drunk drivers arrested on any given date in the lunar month; he believes this number was arrived at by dividing 4,512 by 28 (rather than 29.53, the length of a lunar month) and hence should be 153, not 161.

 Lunar Club Introduction
The Lunar Club introduces amateur astronomers to that object in the sky that most of us take for granted, and which deep sky observers have come to loathe.
Finally, the Lunar Club was created as a project that can easily be done by schools and school children, especially those in the inner city.
As a matter of fact, to prove that the Lunar Club could be done with small apertures, we used 7x35 binoculars and a 60mm refractor.

 Chinese Lunar Base
At Expo 2000 at Hannover the centre piece of the Chinese pavilion was a display of two Chinese astronauts planting the flag of the People’s Republic on the lunar surface.
The direct landing approach was shown in Russian studies of the 1970’s to be the most practical method for emplacment and support of a lunar base (since lunar orbit rendezvous methods restrict possible base locations to a narrow band around the lunar equator).
A lunar landing stage developed for a Shenzhou-derived return vehicle could also be used on a one-way trip to place moon base payloads of about 11 tonnes on the lunar surface.

 Lunar Calendar in Japan
Obviously, the first day of a lunar "month" could sometimes differ for cultures with different longitudes; thus a lunar calendar based on longitude in China would not necessarily be accurate for Japan.
While a lunar calendar was "officially" established in Japan in 692 by the Emperor "Jitou", accurate methods of astronomical observation and calculation found little acceptance.
For example, the lunar October, 1664 is recorded with 30 days, yet there was an actual new moon on the "30th"; thus it should have become lunar November 1st.
