83 Beatrix
Beatrix (minor planet designation: 83 Beatrix) is a fairly large asteroid orbiting in the inner part of the main asteroid belt. It was discovered by Annibale de Gasparis on April 26, 1865. It was his last asteroid discovery. A diameter of at least was determined from the Beatrician stellar occultation observed on June 15, 1983. It is named for Beatrice Portinari, beloved of Dante Alighieri and immortalized by him in ''La Vita Nuova'' and ''The Divine Comedy''. On February 16, 2001, an occultation of a magnitude +9.09 star by this asteroid was observed from three locations. The resulting chords matched an elliptical profile with a mean radius of 35.9 km. The observers noted some dimming and flickering at the beginning of the event, which may indicate the star was binary or the asteroid has an irregular shape. Previous occultations had been observed in 1983 and 1990, which produced a much larger size estimate of 81.4 km. left, Beatrician orbit References External l ...

Annibale De Gasparis
Annibale de Gasparis (9 November 1819, Bugnara – 21 March 1892, Naples; ) was an Italian astronomer, known for discovering asteroids and his contributions to theoretical astronomy. Biography De Gasparis was born in 1819 in Bugnara to Angelo de Gasparis and Eleonora Angelantoni originally from Tocco da Casauria. Son of a doctor, he studied in the seminars of Sulmona and Chieti, becoming passionate of classic novels and learning mathematics as a self-taught person. In 1838 he arrived in Naples to study engineering at the School of Bridges and Roads, today's Engineering faculty of Naples University, and the following year he was accepted as a student at the Astronomical Observatory of Capodimonte by the director Ernesto Capocci. He studied mathematics and celestial mechanics and in 1845 he published his first scientific paper on the orbit of the minor planet Vesta. For this studies he earned, as early as 1846, the honorary degree in mathematics by the University of Naples. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''. 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 (U+1F775 🝵). Occultations by the Moon The term occultation is most frequently used to describe lunar occultations, those relativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-type Asteroids (Tholen)
The X-group of asteroids collects together several types with similar spectra, but probably quite different compositions. Tholen classification In the Tholen classification the X-group consists of the following types: * E-type – with high albedo (> 0.30), composed of enstatite, forsterite and feldspar. They are found in the inner main-belt. * M-type – the largest grouping, intermediate albedo, "metallic", composed of iron and nickel, thought to be the progenitors of nickel–iron meteorites. They are found around 3.0 AU and in the Hungaria region (innermost main-belt). * P-type – low albedos (< 0.10) with featureless red spectra; presumably composed of carbonaceous chondrites, and found in the outer main-belt and in the Jupiter trojan region. Since in this scheme the albedo is crucial in discriminating between the above types, some objects for which albedo information was not available were assigned an X-type. An example of this is 50 Virginia. SMASS class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Divine Comedy
The ''Divine Comedy'' ( it, Divina Commedia ) is an Italian narrative poem by Dante Alighieri, begun 1308 and completed in around 1321, shortly before the author's death. It is widely considered the pre-eminent work in Italian literature and one of the greatest works of world literature. The poem's imaginative vision of the afterlife is representative of the medieval worldview as it existed in the Western Church by the 14th century. It helped establish the Tuscan language, in which it is written, as the standardized Italian language. It is divided into three parts: ''Inferno'', ''Purgatorio'', and '' Paradiso''. The narrative takes as its literal subject the state of the soul after death and presents an image of divine justice meted out as due punishment or reward, and describes Dante's travels through Hell, Purgatory, and Heaven. Allegorically, the poem represents the soul's journey towards God, beginning with the recognition and rejection of sin (''Inferno''), followed by ...

La Vita Nuova
''La Vita Nuova'' (; Italian for "The New Life") or ''Vita Nova'' (Latin title) is a text by Dante Alighieri published in 1294. It is an expression of the medieval genre of courtly love in a prosimetrum style, a combination of both prose and verse. History and context Referred to by Dante as his ''libello'', or "little book," ''La Vita Nuova'' is the first of two collections of verse written by Dante in his life. The collection is a ''prosimetrum'', a piece containing both verse and prose, in the vein of Boethius' ''Consolation of Philosophy''. Dante used each ''prosimetrum'' as a means for combining poems written over periods of roughly ten years—''La Vita Nuova'' contains his works from before 1283 to roughly 1293. The collection and its style fit in with the movement called ''dolce stil novo''. The prose creates the illusion of narrative continuity between the poems; it is Dante's way of reconstructing himself and his art in terms of his evolving sense of the limitations ...

Dante Alighieri
Dante Alighieri (; – 14 September 1321), probably baptized Durante di Alighiero degli Alighieri and often referred to as Dante (, ), was an Italian poet, writer and philosopher. His ''Divine Comedy'', originally called (modern Italian: ''Commedia'') and later christened by Giovanni Boccaccio, is widely considered one of the most important poems of the Middle Ages and the greatest literary work in the Italian language. Dante is known for establishing the use of the vernacular in literature at a time when most poetry was written in Latin, which was accessible only to the most educated readers. His ''De vulgari eloquentia'' (''On Eloquence in the Vernacular'') was one of the first scholarly defenses of the vernacular. His use of the Florentine dialect for works such as '' The New Life'' (1295) and ''Divine Comedy'' helped establish the modern-day standardized Italian language. His work set a precedent that important Italian writers such as Petrarch and Boccaccio would later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star
A star is an astronomical object comprising a luminous spheroid of plasma (physics), plasma held together by its gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night, but their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements.

Beatrice Portinari
Beatrice "Bice" di Folco Portinari (; 1265 – 8 or 19 June 1290) was an Italian woman who has been commonly identified as the principal inspiration for Dante Alighieri's ''Vita Nuova'', and is also identified with the Beatrice who acts as his guide in the last book of his narrative poem the ''Divine Comedy'' (''La Divina Commedia''), '' Paradiso'', and during the conclusion of the preceding ''Purgatorio''. In the ''Comedy'', Beatrice symbolises divine grace and theology. Biography Beatrice was the daughter of the banker Folco Portinari and was married to another banker, Simone dei Bardi. Dante claims to have met a "Beatrice" only twice, on occasions separated by nine years, but was so affected by the meetings that he carried his love for her throughout his life. The tradition that identifies Bice di Folco Portinari as the Beatrice loved by Dante is now widely, though not unanimously, accepted by scholars. Boccaccio, in his commentary on the ''Divine Comedy'', was the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
