Zagut (crater)
Zagut (Zacut) is a crater located in the heavily impacted southeast sector of the Moon. It is almost surrounded by other named craters, with Wilkins to the northwest, Lindenau to the east, Rabbi Levi in the southeast, and Celsius to the southwest. It is named after Jewish Spanish astronomer and rabbi Abraham Zacuto Abraham Zacuto (, ; 12 August 1452 – ) was a Sephardic Jewish astronomer, astrologer, mathematician, rabbi and historian. Born in Castile, he served as Royal Astronomer to King John II of Portugal before fleeing to Tunis. His astrolabe of cop .... The rim of Zagut (Zacut) is worn and irregular, especially to the north and east. The east rim is overlain by Zagut E, a crater with an irregular and flat floor. The floor of Zagut itself is also relatively flat, and the center is occupied by the crater Zagut A instead of a peak.

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilkins (crater)
Wilkins is a lunar impact crater that lies in the rugged highlands in the southeastern part of the Moon's near side. It is located to the southwest of the crater Pons and the long Rupes Altai Rupes Altai is an escarpment in the lunar surface that is located in the southeastern quadrant of the Moon's near side. It is named for the Altai Mountains in Asia, and is the most prominent lunar escarpment. The selenographic coordinates of this ... scarp. Just to the southeast lies the larger crater Zagut, and to the north-northwest is the still-larger Sacrobosco. Wilkins is 57 kilometers in diameter. The outer rim of Wilkins has received considerable damage, leaving sections nearly disintegrated. The most intact portion is in the south, although even this rim is worn and has a valley to the southwest. There is a narrow curving gap in the western rim, with the northern edge formed by a pair of small, joined craters that include Wilkins A. The rim to the northeast barely survives, and t ...

Lindenau (crater)
Lindenau is a Lunar craters, lunar impact crater. It is located beside the east-southeastern rim of the crater Zagut (crater), Zagut, and to the northeast of Rabbi Levi (crater), Rabbi Levi. To the northeast is the slightly smaller crater Rothmann (crater), Rothmann and the Rupes Altai escarpment, scarp. The rim of this crater has received very little wear, in contrast to the neighboring craters to the west and southwest. The edge is sharp, with a small outer wikt:rampart, rampart, and there are wiktionary:terrace, terraces along parts of the interior wall. Along the western edge is a small outward protrusion where the inner face has slumped somewhat. The interior floor is irregular in places, and there is a formation of central peaks about the midpoint. It is from the Upper Imbrian period, 3.8 to 3.2 billion years ago. It is named after 19th century Germany, German astronomer Bernhard von Lindenau. Satellite craters By convention these features are identified on lunar maps by ...

Rabbi Levi (crater)
Rabbi Levi is a lunar impact crater that is located among the rugged highlands in the southeastern part of the Moon's near side. Several notable craters are located nearby, including Zagut just to the north-northwest, the heavily impacted Riccius to the southeast, and Lindenau to the northeast next to Zagut. This is a heavily worn and eroded crater formation, with several smaller craters lying along the incised rim and across the interior floor. A group of these craters form a cluster in the western part of the floor, consisting of the satellite craters A, L, M, and D, as well as lesser craterlets trailing away to the south-southeast. The largest of these craters is Rabbi Levi L, a bowl-shaped formation just to the northwest of the midpoint. The remainder of the floor is relatively level and nearly featureless. Clusters of craters also lay across the eastern and southwestern sections of the rim. Attached to the northeast is the remnant of an old formation that intrudes into R ...

Jews
Jews (, , ), or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of History of ancient Israel and Judah, ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by all ethnic Jews. Despite this, religious Jews regard Gerim, converts to Judaism as members of the Jewish nation, pursuant to the Conversion to Judaism, long-standing conversion process. The Israelites emerged from the pre-existing Canaanite peoples to establish Kingdom of Israel (Samaria), Israel and Kingdom of Judah, Judah in the Southern Levant during the Iron Age.John Day (Old Testament scholar), John Day (2005), ''In Search of Pre-Exilic Israel'', Bloomsbury Publishing, pp. 47.5 [48] 'In this sense, the emergence of ancient Israel is viewed not as the cause of the demise of Canaanite culture but as its upshot'.
