For precise applications, many coordinate systems have been defined for the Moon, each with a slightly different prime meridian. The IAU recommends the "mean Earth/polar axis" system, [ 1 ] in which the prime meridian is the average direction (from the Moon's center) of the Earth's center.
In 1750, Johann Meyer produced the first reliable set of lunar coordinates that permitted astronomers to locate lunar features. [citation needed] Lunar mapping became systematic in 1779 when Johann Schröter began meticulous observation and measurement of lunar topography.
It is located at selenographic coordinates 37.56° N, 30.8° E, and has a diameter of 424.76 kilometers. [1] The name is Latin for Lake of Dreams, a title given to this feature by Giovanni Riccioli. [2] It is the largest of the lunar features designated Lacus. Lacus Somniorum is an irregular feature with complex, somewhat ill-defined borders.
The latitudes and longitudes are in selenographic coordinates. Albedo. These features have a high albedo compared to the surrounding terrain. Name Coordinates
The western rim projects into the near side of the Moon, as defined by the selenographic coordinate system. However the visibility of this formation depends on the effects of libration, so that it can be brought fully into view or completely hidden depending on the orientation of the Moon. When visible, however, it is seen nearly from the side ...
The selenographic coordinates of this feature are 15.0° S, 69.0° W, and it lies within a diameter of 90 km. The lake has a combined surface area in the order of 400 km 2 . [ 1 ]
The selenographic coordinates of this range are . It continues for a distance of 160 kilometres. This range is a long, slender ridge formation that is more rugged at the northeastern end. There is also a rise at the southwest terminus of the range.
The selenographic coordinates of this feature are 11.7° N, 17.9° E. It has a diameter of 112 km. [1] Sinus Honoris has a wide mouth and is bordered by uneven terrain to the north and southwest. Where the bay joins the mare, rille systems extend to the north and south.
