12696 Camus
12696 Camus, provisional designation ', is a carbonaceous background asteroid from the central region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 26 September 1989, by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile, and named after French Nobel Prize laureate in literature Albert Camus. Classification and orbit ''Camus'' is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,551 days). Its orbit has an eccentricity of 0.14 and an inclination of 8 ° with respect to the ecliptic. The asteroid's observation arc begins with its discovery, as no precoveries were taken and no identifications were made before 1989. Naming This minor planet was named after French philosopher, author, and journalist, Albert Camus (1913–1960), who received the Nobel Prize in Literature in 1957. ...

Eric Elst
Eric Walter Elst (30 November 1936 – 2 January 2022) was a Belgian astronomer at the Royal Observatory of Belgium in Uccle and a prolific discoverer of asteroids. The Minor Planet Center ranks him among the top 10 discoverers of minor planets with thousands of discoveries made at ESO's La Silla Observatory in northern Chile and at the Rozhen Observatory in Bulgaria during 1986–2009. The minor planet 3936 Elst, a stony Vestian asteroid from the inner regions of the asteroid belt, roughly 6 kilometers in diameter, was named in his honour. Discoveries Elst is credited by the Minor Planet Center with the discovery of 3866 numbered minor planets made between 1986 and 2009. Notable discoveries include 4486 Mithra, a near-Earth and Apollo asteroid, 7968 Elst-Pizarro, which is classified as both asteroid and comet, and more than 25 Jupiter trojans. His discoveries also include: * binary asteroids such as 4492 Debussy and 15268 Wendelinefroger, * Amor asteroids such as 2 ...

Ecliptic
The ecliptic or ecliptic plane is the orbital plane of the Earth around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. The ecliptic is an important reference plane and is the basis of the ecliptic coordinate system. Sun's apparent motion The ecliptic is the apparent path of the Sun throughout the course of a year. Because Earth takes one year to orbit the Sun, the apparent position of the Sun takes one year to make a complete circuit of the ecliptic. With slightly more than 365 days in one year, the Sun moves a little less than 1° eastward every day. This small difference in the Sun's position against the stars causes any particular spot on Earth's surface to catch up with (and stand directly north or south of) the Sun about four minutes later each day than it would if Earth did not orbit; a day on Earth is therefore 24 hours ...

Magnitude (astronomy)
In astronomy, magnitude is a unitless measure of the brightness Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, ... of an astronomical object, object in a defined passband, often in the visible spectrum, visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. The scale is Logarithmic scale, logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is \sqrt[5] \approx 2.512 times brighter than the magnitude 1 higher. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values. Astronomers use two different defini ...

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 ...

Lightcurve
In astronomy, a light curve is a graph of light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y axis and with time on the x axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic variables, and transiting extrasolar planets, or aperiodic, like the light curve of a nova, a cataclysmic variable star, a supernova or a microlensing event or binary as observed during occultation events. The study of the light curve, together with other observations, can yield considerable information about the physical process that produces it or constrain the physical theories about it. Variable stars Graphs of the apparent magnitude of a variable star over time are commonly used to visualise and analyse their behaviour. Although the categorisation of variable star types is increasingly done from their spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Plague (novel)
''The Plague'' (french: La Peste) is a novel by Albert Camus. Published in 1947, it tells the story from the point of view of a narrator of a plague sweeping the French Algerian city of Oran. The narrator remains unknown until the start of the last chapter, chapter 5 of part 5. The novel presents a snapshot of life in Oran as seen through the author's distinctive Absurdism, absurdist point of view. Camus used as source material the 1846–1860 cholera pandemic, cholera epidemic that killed a large proportion of Oran's population in 1849, but situated the novel in the 1940s. Oran and its surroundings were struck by disease several times before Camus published his novel. According to an academic study, Oran was decimated by the bubonic plague in 1556 and 1678, but all later outbreaks (in 1921: 185 cases; 1931: 76 cases; and 1944: 95 cases) were very far from the scale of the epidemic described in the novel. ''The Plague'' is considered an existentialist classic despite Camus' obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Stranger (Camus Novel)
''The Stranger'' (french: links=no, L'Étranger ), also published in English as ''The Outsider'', is a 1942 novella by French author Albert Camus. Its theme and outlook are often cited as examples of Camus' philosophy, absurdism, coupled with existentialism; though Camus personally rejected the latter label. The title character is Meursault, an indifferent French settler in Algeria described as "a citizen of France domiciled in North Africa, a man of the Mediterranean, an ''homme du midi'' yet one who hardly partakes of the traditional Mediterranean culture."From Cyril Connolly's introduction to the first English translation, by Stuart Gilbert (1946) Weeks after his mother's funeral, he kills an Arab man in French Algiers, who was involved in a conflict with one of Meursault's neighbors. Meursault is tried and sentenced to death. The story is divided into two parts, presenting Meursault's first-person narrative view before and after the murder, respectively. In January 1955, ...
