11020 Orwell
11020 Orwell, provisional designation , is a background asteroid from the outer regions of the asteroid belt, approximately 14 kilometers in diameter. It was discovered on 31 July 1984, by Czech astronomer Antonín Mrkos at Kleť Observatory in the Czech Republic. The asteroid was named after English writer George Orwell. Classification and orbit ''Orwell'' orbits the Sun in the outer main-belt at a distance of 2.6–3.6 AU once every 5 years and 6 months (1,993 days). Its orbit has an eccentricity of 0.15 and an inclination of 3 ° with respect to the ecliptic. It was first observed as at Crimea–Nauchnij in 1979, extending the body's observation arc by 5 years prior to its official discovery observation at Klet. Physical characteristics According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, ''Orwell'' measures 14.466 kilometers in diameter and its surface has an albedo of 0.089. It has an absolute mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonín Mrkos
Antonín Mrkos () (27 January 1918, Střemchoví – 29 May 1996, Prague) was a Czechs, Czech astronomer. Biography Mrkos entered the University in Brno in 1938. His studies were interrupted by the onset of World War II, and in 1945 he became a staff member at the Skalnaté Pleso Observatory in Slovakia. It was from here that he carried out his extremely active cometary programme and became the discoverer of several unusual comets, the most famous of them the bright Comet 1957d. He was the second Czech in Antarctica and the first Czechoslovak to reach the Southern Pole of Inaccessibility as a member of the 3rd Soviet Antarctic Expedition (1957–1959). The Czechoslovakian flag was the second flag raised after the flag of the USSR. He returned to Antarctica as the head of the four-member Czechoslovakian crew in the seventh List of Antarctic expeditions by the Soviet Union, Soviet Antarctic Expedition (1961–1963). He was studying aurora (astronomy), auroras among other thin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide-field Infrared Survey Explorer
Wide-field Infrared Survey Explorer (WISE, observatory code C51, Explorer 92 and SMEX-6) is a NASA infrared astronomy space telescope in the Explorers Program. It was launched in December 2009, and placed in hibernation mode in February 2011, before being re-activated in 2013 and renamed the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). WISE discovered thousands of minor planets and numerous star clusters. Its observations also supported the discovery of the first Y-type brown dwarf and Earth trojan asteroid. WISE performed an all-sky astronomical survey with images in 3.4, 4.6, 12 and 22 μm wavelength range bands, over ten months using a diameter infrared telescope in Earth orbit. After its solid hydrogen coolant depleted, a four-month mission extension called NEOWISE was conducted to search for near-Earth objects (NEO) such as comets and asteroids using its remaining capability. The WISE All-Sky (WISEA) data, including processed images, source cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animal Farm
''Animal Farm'' is a beast fable, in the form of satirical allegorical novella, by George Orwell, first published in England on 17 August 1945. It tells the story of a group of farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy. Ultimately, the rebellion is betrayed, and the farm ends up in a state as bad as it was before, under the dictatorship of a pig named Napoleon. According to Orwell, ''Animal Farm'' reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union. Orwell, a democratic socialist, was a critic of Joseph Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the May Days conflicts between the POUM and Stalinist forces during the Spanish Civil War. In a letter to Yvonne Davet, Orwell described ''Animal Farm'' as a satirical tale against Stalin ("'"), and in his essay "Why I W ...

Nineteen Eighty-Four
''Nineteen Eighty-Four'' (also stylised as ''1984'') is a dystopian social science fiction novel and cautionary tale written by the English writer George Orwell. It was published on 8 June 1949 by Secker & Warburg as Orwell's ninth and final book completed in his lifetime. Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist, modelled the authoritarian state in the novel on Stalinist Russia and Nazi Germany. More broadly, the novel examines the role of truth and facts within societies and the ways in which they can be manipulated. The story takes place in an imagined future in the year 1984, when much of the world is in perpetual war. Great Britain, now known as Airstrip One, has become a province of the totalitarian superstate Oceania, which is led by Big Brother, a dictatorial leader supported by an intense cult of personality manufactured by ...

Dystopia
A dystopia (from Ancient Greek δυσ- "bad, hard" and τόπος "place"; alternatively cacotopiaCacotopia (from κακός ''kakos'' "bad") was the term used by Jeremy Bentham in his 1818 Plan of Parliamentary Reform (Works, vol. 3, p. 493). or simply anti-utopia) is a speculated community or society that is undesirable or frightening. It is often treated as an Opposite (semantics), antonym of ''utopia'', a term that was coined by Sir Thomas More and figures as the title of his best known work, published in 1516, which created a blueprint for an ideal society with minimal crime, violence and poverty. The relationship between utopia and dystopia is in actuality not one simple opposition, as many utopian elements and components are found in dystopias as well, and ''vice versa''. Dystopias are often characterized by rampant fear or distress , tyrannical governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society.

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

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 ...

Asteroid Spectral Type
An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo. These types are thought to correspond to an asteroid's surface composition. For small bodies that are not internally differentiated, the surface and internal compositions are presumably similar, while large bodies such as Ceres and Vesta are known to have internal structure. Over the years, there has been a number of surveys that resulted in a set of different taxonomic systems such as the Tholen, SMASS and Bus–DeMeo classifications. Taxonomic systems In 1975, astronomers Clark R. Chapman, David Morrison, and Ben Zellner developed a simple taxonomic system for asteroids based on color, albedo, and spectral shape. The three categories were labelled " C" for dark carbonaceous objects, " S" for stony (silicaceous) objects, and "U" for those that did not fit into either C or S. This basic division of asteroid spectra has since been expanded and clarified.Thomas H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
