Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

7097 Yatsuka
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as Symbolism of the Number 7, highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the Brahmi numerals, beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectili ...

__NOTOC__ Year 586 ( DLXXXVI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar.

Hiroshi Abe (astronomer)
is a Japanese amateur astronomer affiliated with the Yatsuka Observatory. He is noted for numerous discoveries, including his 2007 discovery of the Nova Vulpeculae, and 28 numbered minor planets during 1993–1999. The main-belt asteroid 5379 Abehiroshi, discovered by Osamu Muramatsu in 1991 is named in his honor. The official naming citation was published by the Minor Planet Center The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU).

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They 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 usually 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 C ...

Minor Planet Center
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...

Main-belt
The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. About 60% of its mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is calculated to be 3% that of the Moon. Ceres, the only object in the asteroid belt large enough to be a dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters less than 600 km. The remaining bodies range down to the size of a dust particle. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takao Kobayashi
is a Japanese amateur astronomer and an outstanding discoverer of minor planets who currently works at the Ōizumi Observatory. The asteroid 3500 Kobayashi is named after him. Career Kobayashi has discovered more than 2000 asteroids using CCD technology, including the Amor asteroids 7358 Oze, , and about nine Trojan asteroids. He also discovered the periodic comet P/1997 B1 (Kobayashi), which he originally reported as an asteroid. His asteroid discoveries of January 16, 1994 and December 31, 1994, have been named 8883 Miyazakihayao and 10160 Totoro by Kobayashi. The names reference anime filmmaker Hayao Miyazaki, and one of his creations, ''My Neighbor Totoro''. The names were approved by the International Astronomical Union. Kobayashi is not to be confused with another Japanese astronomer, Toru Kobayashi, who co-discovered comet C/1975 N1 (Kobayashi-Berger-Milon). P/1997 B1 Kobayashi On January 30 and January 31, 1997, Kobayashi observed an object, P/1997 B1 Koba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
