25. Rmer

Mountainess area bordering the Sea of Tranquility, and the Sea of Serenity. All around Rmer we see a field of tight packed craters with only few still intact crater walls. In the area Rmer-Charconac-Littrow we find a rille system also visible in smaller telescopes.

FRANZ - Julius Franz (1847 1913) Observed the transit of Venus. Measurements of features near the lunar limbs. Published a book 1906, called "Der Mond". In which he named some lunar mares along the limb the Mare Orientale, Mare Autumni and Mare Veris.

Crater (25km /16Mi ) (Dept: 600m /1,968ft) (16.6N, 40.2E) Eroded rim of generally circular form, interior flooded, leaving only a narrow inner wall and a low rim.

LE MONNIER - Pierre Charles Le Monnier. (1715 -1799) French astronomer. Started observing before he was sixteen, and the presentation of a lunar map resulted in his admission to the French Academy of Sciences, on 21 April 1736, aged only 20.

Crater. (61km /37Mi ) (Dept: 2,400m /7,300ft) (26.6N, 30.6E) Flooded crater with halve its rim missing.

LITTROW - Johann J. von Littrow (1781 - 1840) Austrian astronomer. Director of the Vienna Observatory, created the only conformal retroazimuthal map projection, which is known as the Littrow projection.

Crater. (31km /19Mi ) (Dept: 1,200m /3,600ft) (21.5N, 31.4E) Rim heavily worn and eroded, especially along the southern wall. The interior flooded with lava.

MARALDI - 1. Giancomo Filippo Maraldi (1665 - 1729) Italian mathematician. 2. Giovanni Domenico Maraldi ( 1709 - 1788) Both nephews of Domenico Cassini, with whom they cooperated. And both astronomers in their own right.

Crater. (40km /24Mi ) (Dept: 1,300m/3,900ft) (19.4N 34.9E) Flooded by lava, remnants of a central mountain, outer wall partly destroyed.

NEWCOMBE - Simon Newcomb. (1835 - 1909) Canadian-American astronomer and mathematician. Worked on measuring the speed of light and on time measuring. (Important for navigation).

Crater. (39km /24Mi ) (Depth: 2,180m /6,600ft) (29.9N, 43.8E) Sharp-edged, irregular rim, polygonal more than circular, terraced along the inner side. South-southwestern part of the rim is overlaid by the smaller crater Newcomb A.

RMER - Ole Rmer. (1797 - 1875) Danish astronomer. Made the first quantitative measurements of the speed of light (1676), by observing the times of the eclipses of the moons of Jupiter.

Crater. (40km /24Mi ) (Depth: 3,400m /10,300ft) (25.4N, 36.4E) High walled rim, terraced inner surface, small craterlet on the north part of the floor, large central peak.

MONTES TAURUS - The Taurus mountains. Named  by Johannes Hevelius, (after the Taurus Mountains in southern Turkey).

Mountains. (172Km /107Mi ) (Height: 3,000m /91,000ft) (28.4 N, 41.1 E) At the southwestern edge of the range is the crater Rmer, Newcomb is located in the northeastern section, and  the Taurus-Littrow valley, the landing site of the manned Apollo 17 mission is also located in this area.

MARE TRANQUILLITATIS - Mare Tranquillitatis was named in 1651 by astronomers Francesco Grimaldi and Giovanni Battista Riccioli in their lunar map Almagestum novum.

Mare. (421,000 km ) (721Km /424Mi ) (8.5N, 31.4E) In the western part ridges, and domes, basalt floor. Landing site for the first manned landing on the Moon on July 20, 1969, at 20:18 GMT. At Statio Tranquillitatis.

VITRUVIUS - Pollio Vitruvius (ca. 75 - 15 BC ) Roman architect and author of "Archtectura" a work about amongst other matters, astronomy.

Crater. (31km /18Mi ) (Dept: 1,550m /4,700ft) (17.6N, 31.3E) The interior floor is uneven and a small crater is attached to southern outer rim. Almost circular.
