65 Cybele
Cybele, minor planet designation 65 Cybele, is one of the largest asteroids in the Solar System. It is located in the outer asteroid belt. It is thought to be a remnant primordial body. It gives its name to the Cybele group of asteroids that orbit outward from the Sun from the 2:1 orbital resonance with Jupiter. The X-type asteroid has a relatively short rotation period of 6.0814 hours. It was discovered by Wilhelm Tempel in 1861, and named after Cybele, the earth goddess. Discovery and naming ''Cybele'' was discovered on 8 March 1861, by German astronomer Wilhelm Tempel from the Marseilles Observatory in southeastern France. A minor controversy arose from its naming process. Tempel had awarded the honour of naming the asteroid to Carl August von Steinheil in recognition of his achievements in telescope production. Von Steinheil elected to name it "Maximiliana" after the reigning monarch Maximilian II of Bavaria. At the time, asteroids were conventionally given classical ...

Wilhelm Tempel
Ernst Wilhelm Leberecht Tempel (4 December 1821 – 16 March 1889), normally known as Wilhelm Tempel, was a German astronomer who worked in Marseille until the outbreak of the Franco-Prussian War in 1870, then later moved to Italy. Tempel was born at Niedercunnersdorf, Saxony. He was a prolific discoverer of comets, discovering or co-discovering 21 in all, including Comet 55P/Tempel-Tuttle, now known to be the parent body of the Leonids, Leonid meteor shower, and 9P/Tempel, the target of the NASA probe ''Deep Impact (spacecraft), Deep Impact'' in 2005. Other periodic comets that bear his name include 10P/Tempel and 11P/Tempel-Swift-LINEAR. In 1861, he was awarded the Lalande Prize. He won the Valz Prize, Prix Valz for the year 1880. The main-belt asteroid 3808 Tempel and the lunar crater ''Tempel (crater), Tempel'' are named after him. References External links * * W.

List Of Notable Asteroids
The following is a collection of lists of asteroids of the Solar System that are exceptional in some way, such as their size or orbit. For the purposes of this article, "asteroid" refers to minor planets out to the orbit of Neptune, and includes the dwarf planet 1 Ceres, the Jupiter trojans and the centaurs, but not trans-Neptunian objects (objects in the Kuiper belt, scattered disc or inner Oort cloud). For a complete list of minor planets in numerical order, see List of minor planets. Background Asteroids are given minor planet numbers, but not all minor planets are asteroids. Minor planet numbers are also given to objects of the Kuiper belt, which is similar to the asteroid belt but farther out (around 30–60 AU), whereas asteroids are mostly between 2–3 AU from the Sun and at the orbit of Jupiter 5 AU from the Sun. Also, comets are not typically included under minor planet numbers, and have their own naming conventions. Asteroids are given a uniqu ...

64 Angelina
Angelina (minor planet designation: 64 Angelina) is an asteroid from the central region of the asteroid belt, approximately 50 kilometers in diameter. It is an unusually bright form of E-type asteroid. Discovery and naming Angelina was discovered on March 4, 1861, by a prolific comet discoverer, E. W. Tempel, observing from Marseilles, France. It was the first of his five asteroid discoveries. The naming of Angelina caused some controversy. It was chosen by Benjamin Valz, director of the Marseilles Observatory, in honour of the astronomical station of that name operated by Baron Franz Xaver von Zach on the mountains above the city. At the time, asteroids were supposed to receive names from classical mythology, and several astronomers protested the choice. Tempel noted that if the second 'n' were removed, the complaints would be satisfied (referring to Angelia, a minor Greek deity). However, Valz's choice stayed.

54 Alexandra
Alexandra (minor planet designation: 54 Alexandra) is a carbonaceous asteroid from the intermediate asteroid belt, approximately 155 kilometers in diameter. It was discovered by German-French astronomer Hermann Goldschmidt on 10 September 1858, and named after the German explorer Alexander von Humboldt; it was the first asteroid to be named after a male. Description On May 17, 2005, this asteroid occulted a faint star ( magnitude 8.5) and the event was observed and timed in a number of locations within the U.S. and Mexico. As a result, a silhouette profile was produced, yielding a roughly oval cross-section with dimensions of 160 × 135 km (± 1 km).D.W. Dunham, "Upcoming Asteroid Occultations", ''Sky & Telescope'', June, 2006, p. 63. The mass of the asteroid can be estimated based upon the mutually perturbing effects of other bodies, yielding an estimate of . Photometric observations of this asteroid during 1990–92 gave a light curve with a period of 18. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
45 Eugenia
Eugenia (minor planet designation: 45 Eugenia) is a large asteroid of the asteroid belt. It is famed as one of the first asteroids to be found to have a moon orbiting it. It was also the second triple asteroid to be discovered, after 87 Sylvia. Discovery Eugenia was discovered on 27 June 1857 by the Franco-German amateur astronomer Hermann Goldschmidt. His instrument of discovery was a 4-inch aperture telescope located in his sixth floor apartment in the 6th Arrondissement of Paris. It was the forty-fifth minor planet to be discovered. The preliminary orbital elements were computed by Wilhelm Forster in Berlin, based on three observations in July, 1857. The asteroid was named by its discoverer after Empress Eugenia di Montijo, the wife of Napoleon III. It was the first asteroid to be definitely named after a real person, rather than a figure from classical legend. Physical characteristics Eugenia is a large asteroid, with a diameter of 214 km. It is an F-type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phrygia
In classical antiquity, Phrygia ( ; grc, Φρυγία, ''Phrygía'' ) was a kingdom in the west central part of Anatolia, in what is now Asian Turkey, centered on the Sangarios River. After its conquest, it became a region of the great empires of the time. Stories of the heroic age of Greek mythology tell of several legendary Phrygian kings: * Gordias, whose Gordian Knot would later be cut by Alexander the Great * Midas, who turned whatever he touched to gold * Mygdon, who warred with the Amazons According to Homer's ''Iliad'', the Phrygians participated in the Trojan War as close allies of the Trojans, fighting against the Achaeans. Phrygian power reached its peak in the late 8th century BC under another, historical, king Midas, who dominated most of western and central Anatolia and rivaled Assyria and Urartu for power in eastern Anatolia. This later Midas was, however, also the last independent king of Phrygia before Cimmerians sacked the Phrygian capital, Go ...

Maximilian II Of Bavaria
Maximilian II (28 November 1811 – 10 March 1864) reigned as King of Bavaria between 1848 and 1864. Unlike his father, King Ludwig I, "King Max" was very popular and took a greater interest in the business of Government than in personal extravagance. Ascending the throne during the German Revolution of 1848, King Maximilian restored stability in his kingdom. The rest of his reign was characterized by attempts to maintain Bavarian independence during the wars of German Unification and to transform his capital city of Munich into a cultural and educational city. Crown Prince He was born in Munich and was the eldest son of the Crown Prince of Bavaria (later King Ludwig I) and his wife Therese of Saxe-Hildburghausen. After studying at Göttingen and Berlin and travelling in Germany, Italy and Greece, he was introduced by his father into the council of state (1836). From the first he showed a studious disposition, declaring on one occasion that had he not been born in a royal crad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...

Carl August Von Steinheil
Carl August von Steinheil (12 October 1801 – 14 September 1870) was a German physicist, inventor, engineer and astronomer. Biography Steinheil was born in Ribeauvillé, Alsace. He studied law in Erlangen since 1821. He then studied astronomy in Göttingen and Königsberg. He continued his studies in astronomy and physics while living in his father's manor in Perlachseck near Munich. From 1832 to 1849, Steinheil was professor for mathematics and physics at the University of Munich. In 1839, Steinheil used silver chloride and a cardboard camera to make pictures in negative from the Museum of Art and the Munich Frauenkirche, then taking another picture of the negative to get a positive, the actual black and white reproduction of a view on the object. The pictures produced were round with a diameter of 4 cm, the method was later named the “Steinheil method.” It was the first daguerreotype in Germany. In 1846, Steinheil travelled to Naples to install a new system for weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marseilles Observatory
Marseille Observatory (french: Observatoire de Marseille) is an astronomical observatory located in Marseille, France, with a history that goes back to the early 18th century. In its 1877 incarnation, it was the discovery site of a group of galaxies known as Stephan's Quintet, discovered by its director Édouard Stephan. Marseille Observatory is now run as a joint research unit by Aix-Marseille University and the French National Center for Scientific Research (CNRS). The old Palais Longchamps facilities are a noted tourist destination in Marseilles area, and a planetarium was also added in 2001. One of the noted exhibits is the Foucault glass-mirror telescope, and various items from centuries of astronomical activities. Foucault's telescope is a noted historical example because it was the forerunner of the modern style of big reflecting telescopes which use a minute layer of metal on a figured piece of glass. Before this, the main technology was to make the whole mirror of meta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation Period
The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the background stars, measured in sidereal time. The other type of commonly used rotation period is the object's synodic rotation period (or ''solar day''), measured in solar time, which may differ by a fraction of a rotation or more than one rotation to accommodate the portion of the object's orbital period during one day. Measuring rotation For solid objects, such as rocky planets and asteroids, the rotation period is a single value. For gaseous or fluid bodies, such as stars and gas giants, the period of rotation varies from the object's equator to its pole due to a phenomenon called differential rotation. Typically, the stated rotation period for a gas giant (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as d ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth the mass of the Sun. Jupiter is the List of brightest natural objects in the sky, third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since Pre-history, prehistoric times. It was named after the Jupiter (mythology), Roman god Jupiter, the king of the gods. Jupiter is primarily composed of hydrogen, but helium constitutes one-quarter of its mass and one-tenth of its volume. It probably has a rocky core of heavier elements, but, like the other giant planets in the Solar System, it lacks a well-defined solid surface. The ongoing contraction of Jupiter's interior generates more heat than it receives from the Sun. Because of its rapid rotation, the planet' ...
