Zagut (crater)
Zagut 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 ( he, , translit=Avraham ben Shmuel Zacut, pt, Abraão ben Samuel Zacuto; 12 August 1452 – ) was a Castilian astronomer, astrologer, mathematician, rabbi and historian who served as Royal Astronomer to King John II of Portugal. .... The rim of Zagut 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. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Z ...

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 occu ...

Abraham Zacuto
Abraham Zacuto ( he, , translit=Avraham ben Shmuel Zacut, pt, Abraão ben Samuel Zacuto; 12 August 1452 – ) was a Castilian astronomer, astrologer, mathematician, rabbi and historian who served as Royal Astronomer to King John II of Portugal. His astrolabe of copper, his astronomical tables and maritime charts played an important role in the Spanish and Portuguese navigation capability. They were used by Vasco Da Gama and Christopher Columbus. The crater Zagut on the Moon is named after him. Life Zacuto was born in Salamanca, Castile in 1452. He may have studied and taught astronomy at the University of Salamanca. He later taught astronomy at the universities of Zaragoza and then Carthage. He was well versed in Jewish Law, and was the rabbi of his community. With the Catholic Monarchs of Spain issuing the 1492 Alhambra Decree ordering the expulsion of the Jews, Zacuto took refuge in Lisbon, Portugal. Already famous in academic circles, he was invited to court and nom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity 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. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, 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, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...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 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 the rim here is low and scarred by valleys and old craters. The interior floor of Wilkins is relatively flat and featureless, except for a ghost-crater rim along the southwest edge. The ray material from Tycho lies north of the crater rim. The crater i ...

Lindenau (crater)
Lindenau is a lunar impact crater. It is located beside the east-southeastern rim of the crater Zagut, and to the northeast of Rabbi Levi. To the northeast is the slightly smaller crater Rothmann and the Rupes Altai 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 rampart, and there are 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 German astronomer Bernhard von Lindenau Baron Bernhard August von Lindenau (11 June 1779 – 21 May 1854) was a German lawyer, astronomer, politician, and art collector. Lindenau was born in Altenburg, the son of Johann August Lindenau, a reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Ra ...

Celsius (crater)
Celsius is a small lunar impact crater that is located in the rugged terrain in the southern hemisphere on the Moon's near side. It is named after Swedish astronomer, physicist and mathematician Anders Celsius Anders Celsius (; 27 November 170125 April 1744) was a Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germa .... It lies less than one crater diameter to the south-southwest of the crater Zagut, and due north of Büsching. This is a heavily worn crater with a southwest rim that has been damaged by multiple small crater impacts. There is a valley-like gap in the northern rim that joins Celsius with Celsius A. The interior floor of Celsius is almost featureless, except for a small craterlet in the northern half. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater ...

Jews
Jews ( he, יְהוּדִים, , ) or Jewish people are an ethnoreligious group and nation originating from the Israelites Israelite origins and kingdom: "The first act in the long drama of Jewish history is the age of the Israelites""The people of the Kingdom of Israel and the ethnic and religious group known as the Jewish people that descended from them have been subjected to a number of forced migrations in their history" and Hebrews of historical History of ancient Israel and Judah, Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, "Historically, the religious and ethnic dimensions of Jewish identity have been closely interwoven. In fact, so closely bound are they, that the traditional Jewish lexicon hardly distinguishes between the two concepts. Jewish religious practice, by definition, was observed exclusively by the Jewish people, and notions of Jewish peoplehood, nation, and community were suffused with faith in the Jewish God, ...
