65 Cybele
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 names, and a number of astro ...

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 Leonid meteor shower, and 9P/Tempel, the target of the NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States ... probe ''Deep Impact (spacecraft), Deep Impact'' in 2005.

Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document.

Asteroid Occultation
An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks from view (occults) an object in the background. In this general sense, occultation applies to the visual scene observed from low-flying aircraft (or computer-generated imagery) when foreground objects obscure distant objects dynamically, as the scene changes over time. If the closer body does not entirely conceal the farther one, the event is called a ''Transit (astronomy), transit''. Both transit and occultation may be referred to generally as ''occlusion''; and if a shadow is cast onto the observer, it is called an eclipse. The symbol for an occultation, and especially a solar eclipse, is file:Occultation symbol.svg, đźťµ (U+1F775 đźťµ).

64 Angelina
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 Marseille, 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 Marseille 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. Physical characteristics Angelina is an uncommon form of E-type asteroid; it is the third larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
54 Alexandra
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 18.14 ± 0.04 hours and a brightness variation o ...

45 Eugenia
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 asteroid, which means that it is very da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phrygia
In classical antiquity, Phrygia ( ; , ''PhrygĂa'') was a kingdom in the west-central part of Anatolia, in what is now Asian Turkey, centered on the Sangarios River. 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, Gordium, around 695 BC. Phrygia then became subject to Lydia, and then successivel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 and declared on one occasion that had he not been born in a roy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescope
A telescope is a device used to observe distant objects by their emission, Absorption (electromagnetic radiation), absorption, or Reflection (physics), reflection of electromagnetic radiation. Originally, it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 July 1839, Steinheil demonstrated a photographic process at Nymphenburg Palace in the presence of Queen Therese. Several photographs had been exhibited by Steinheil throughout April and Summer 1839. The process has been commonly attributed to Steinheil, but research published in 2024 revealed that the earliest paper negatives had actually been created by Wolfgang Franz von Kobell in 1837, without any involvement of Steinheil. Steinheil was one of the first to use the daguerreotype in Germany. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marseilles Observatory
Marseille Observatory () 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 Longchamp facilities are a noted tourist attraction in Marseille, 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 metal, and it would really be another half-ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation Period
In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the '' sidereal rotation period'' (or ''sidereal day''), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars ( inertial space). The other type of commonly used "rotation period" is the object's '' synodic rotation period'' (or ''solar day''), which may differ, by a fraction of a rotation or more than one rotation, to accommodate the portion of the object's orbital period around a star or another body 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 giant planets, 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 giant pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
