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 ...

5881 Akashi
6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies.J. F. Dreyer Jr."The Beam Power Output Tube" New York: McGraw-Hill, ''Electronics'', April 1936, pp. 18 - 21, 35 The 6L6 is a beam tetrode that utilizes formation of a low potential space charge region between the anode and screen grid to return anode secondary emission electrons to the anode and offers significant performance improvements over power pentodes. The 6L6 was the first successful beam power tube marketed. In the 21st century, variants of the 6L6 are manufactured and used in some high fidelity audio amplifiers and musical instrument amplifiers. History In the UK, three engineers at EMI (Isaac Shoenberg, Cabot Bull and Sidney Rodda) had developed and filed patents in 1933 and 1934 on an output tetrode that utilized novel electrode structures to form electron beams to create a dense space charge ...

8892 Kakogawa
__NOTOC__ Year 889 ( DCCCLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. Events By place Europe * Guy III, duke of Spoleto, defeats the Lombard king Berengar I at the Trebbia River, and is acclaimed as king of Italy at an assembly in Pavia. After confirming some privileges to the Catholic Church, he is crowned with the Iron Crown of Lombardy, by Pope Stephen V. Berengar is forced to retreat to Verona; Guy does not pursue him into Friuli, because of the (possible) wrath of King Arnulf of Carinthia. * Boris I, ruler ('' khan'') of the Bulgarian Empire, abdicates the throne after a 37-year reign, and retires to a monastery. He is succeeded by his eldest son Vladimir, as monarch of Bulgaria. Vladimir falls under the influence of the old boyars; many remain anti-Christian and anti-Byzantine.

Kōyō Kawanishi
is a Japanese dentist, amateur astronomer and discoverer of 13 minor planets. He lives in the city of Akō in the Hyōgo Prefecture, Japan, where his private Minami-Oda Observatory () is located. At the observatory, he observes comets and minor planets using his home-made 0.20-m reflector telescope together with his wife Kumi and daughter Saki. Familiar with electronics and mechanics, he has also developed his own CCD instrumentation. The asteroid 5591 Koyo, discovered by Japanese astronomer Takeshi Urata was a Japanese astronomer. He was a prolific discoverer of asteroids, observing at Nihondaira Observatory. In 1978 he became the first amateur to discover a minor planet (2090 Mizuho) in over fifty years, which he named after his daughter, Mizu ..., was named in his honour.

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 ...
