Ladislav Brožek
Ladislav Brožek (born 1952) is a Slovak astronomer. At the Bohemian Kleť Observatory, he discovered a total of 23 minor planets between 1979 and 1982, as credited by the Minor Planet Center. One of his discoveries, the main-belt asteroid 2613 Plzeň, he named after his birthplace Plzeň. In 1981, he discovered 3102 Krok, a near-Earth object of the Apollo asteroid, Apollo group. He also named another of his discoveries, 3834 Zappafrank, in memory of rock musician and composer Frank Zappa (1940–1993).

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 IAU definition of planet, reclassified minor planets and comets into dwarf planets and Small Solar System body, small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006. Accessed May 5, 2008. In contrast to the eight official planets of the Solar System, all minor planets fail to clearing the neighborhood, clear their orbital neighborhood.

Frank Zappa
Frank Vincent Zappa (December 21, 1940 – December 4, 1993) was an American guitarist, composer, and bandleader. In a career spanning more than 30 years, Zappa composed Rock music, rock, Pop music, pop, jazz, jazz fusion, orchestral and ''musique concrète'' works; he additionally produced nearly all the 60-plus albums he released with his band the Mothers of Invention and as a solo artist. His work is characterized by wikt:nonconformity, nonconformity, Musical improvisation, improvisation sound experimentation, Virtuoso, musical virtuosity and satire of American culture. Zappa also directed feature-length films and music videos, and designed album covers. He is considered one of the most innovative and stylistically diverse musicians of his generation. As a mostly self-taught composer and performer, Zappa had diverse musical influences that led him to create music that was sometimes difficult to categorize. While in his teens, he acquired a taste for 20th-century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday experiences. Some discoveries represent a radical breakthrough in knowledge or technology. Others are based on earlier discoveries, collaborations or ideas. In such cases, the process of discovery requires at least the awareness that an existing concept or method could be modified or transformed. New discoveries are made using various senses, and are usually added to pre-existing knowledge. Questioning plays a key role in discovery; discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. Science Within scientific discip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Plzeň
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3102 Krok
3102 Krok, provisional designation , is a rare-type asteroid and slow rotator, classified as a near-Earth object of the Amor group, that measures approximately 1.5 kilometers in diameter. It was discovered on 21 August 1981, by Slovak astronomer Ladislav Brožek at Kleť Observatory in the Czech Republic. The asteroid was named after Duke Krok, a legendary Czech figure. Classification and orbit ''Krok'' orbits the Sun at a distance of 1.2–3.1 AU once every 3 years and 2 months (1,152 days). Its orbit has an eccentricity of 0.45 and an inclination of 8 ° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at Klet, as no precoveries were taken and no prior identifications were made. It has an Earth minimum orbital intersection distance of , which translates into 71.7 lunar distances. Physical characteristics In the Tholen classification, ''Krok'' is characterized as a rare QRS-type. In the SMASS taxonomy it i ...

2696 Magion
2696 Magion, provisional designation , is a dark background asteroid and a slow rotator from the inner regions of the asteroid belt, approximately in diameter. It was discovered on 16 April 1980, by Slovak astronomer Ladislav Brožek at the Kleť Observatory in former Czechoslovakia. The X-type asteroid has an ambiguous rotation period of 480 hours and is possibly a tumbler. It was named for the first Czechoslovak satellite, Magion 1, launched in 1978. Orbit and classification ''Magion'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. Based on osculating Keplerian orbital elements, the asteroid has also been considered a member of the Phocaea family (), a large family with two thousand members, named after 25 Phocaea. It orbits the Sun in the inner asteroid belt at a distance of 2.2–2.7 AU once every 3 years and 10 months (1,401 days; semi-major axis of 2 ...

2613 Plzeň
2613 Plzeň, provisional designation , is an asteroid from the outer region of the asteroid belt, approximately 28 kilometers in diameter. It was discovered on 30 August 1979, by Czech astronomer Ladislav Brožek at the South Bohemian Kleť Observatory in the Czech Republic. It was later named for the Czech city of Plzeň. Orbit and classification ''Plzeň'' orbits the Sun in the outer main-belt at a distance of 2.9–3.2 AU once every 5 years and 4 months (1,937 days). Its orbit has an eccentricity of 0.05 and an inclination of 13 ° with respect to the ecliptic. It was first identified as at Crimea-Nauchnij in 1969. However, ''Plzeň''s observation arc begins with its discovery observation in 1979, as its first identification remained unused. Physical characteristics According to three observations made by the Infrared Astronomical Satellite IRAS and based on observations made by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the a ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses on a specific question or field outside the scope of Earth. Astronomers observe astronomical objects, such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers typically fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate Con ...
