Syuichi Nakano
is a Japanese astronomer. He specializes in the study of comets, in particular calculating their orbits and making predictions about when periodic comets will return for another perihelion approach. It is considerably more difficult to predict the orbits of comets than of other types of Solar System objects, since their orbits are susceptible not only to perturbations from the planets but also to non-gravitational forces due to the release of gaseous material in the form of a comet's coma and tail. He is affiliated with the Computing & Minor Planet Sections (Center for Astrodynamics) of the Oriental Astronomical Association in Sumoto, Japan. He publishes the ''Nakano Notes'' on comet observations and ephemerides. In 2001 he won the Amateur Achievement Award of the Astronomical Society of the Pacific. The asteroid 3431 Nakano is named after him, and asteroid 3983 Sakiko is named after his sister. 1026 Ingrid was reidentified in 1986 by Syuichi Nakano, ending its time as a l ...

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 ...

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 ...

Paul Boltwood
Paul Boltwood (1943 – September 25, 2017) was a Canadian amateur astronomer. He was engaged in developing hardware and software for deep sky imaging and in research of brightness variations in active galactic nuclei. He was also acknowledged for his studies of near-nucleus activity in Comet Hyakutake. Boltwood died in Stittsville, Ontario. Early life and education Paul Boltwood was born in Vancouver, British Columbia in 1943. He first became interested in astronomy around age 12 and had built his own telescope by age 15. He received a bachelor's degree in mathematics from the University of British Columbia in 1966. He pursued a career in computer software and systems design, with an emphasis on signal and image processing. Work in astronomy Paul Boltwood founded Boltwood Systems Corporation in 1980, which manufactured cloud sensors for amateur astronomers. In the early 1990s, he constructed an observatory in his backyard near Ottawa, Ontario, with a CCD camera of his ow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3568 ASCII
3568 ASCII, provisional designation , is a dark background asteroid from the outer regions of the asteroid belt, approximately in diameter. It was discovered on 17 October 1936, by French astronomer Marguerite Laugier at the Nice Observatory in southwestern France. In 1988, the D-type asteroid was named after both the computer character code ASCII and the Japanese computer magazine with the same name. Orbit and classification ''ASCII'' is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer main-belt at a distance of 2.4–3.9 AU once every 5 years and 7 months (2,044 days; semi-major axis of 3.15 AU). Its orbit has an eccentricity of 0.24 and an inclination of 19 ° with respect to the ecliptic. The body's observation arc begins with its observation as at the Karl Schwarzschild Observatory in November 1975, or more than 39 years after its official discovery observation at Nice. Physical characteristics ''ASCII'' ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lost Asteroid
A minor planet is "lost" when today's observers cannot find it, because its location is too uncertain to target observations. This happens if the orbital elements of a minor planet are not known accurately enough, typically because the observation arc for the object is too short, or too few observations were made before the object became unobservable (e.g. too faint due to increasing distance, or too close to the Sun to view at night). By some definitions thousands, if not tens of thousands, of mostly small observed minor planets are lost. Some lost minor planets discovered in decades past cannot be found because the available observational data is insufficient for reliable orbit determination. With limited information astronomers cannot know where to look for the object at future dates. Lost objects are sometimes recovered when serendipitously re-observed by a later astronomical survey. If the orbital elements of the newly found object are sufficiently close to those of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1026 Ingrid
1026 Ingrid, provisional designation , is a stony Florian asteroid and long-lost minor planet (1923–1986) from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered by Karl Reinmuth at Heidelberg in 1923, and later named after Ingrid, niece and godchild of astronomer Albrecht Kahrstedt. Discovery and recovery ''Ingrid'' was discovered on 13 August 1923, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was observed for only a few days during August 1923, before it became a lost minor planet for nearly 63 years until its recovery by Japanese astronomer Syuichi Nakano in 1986. Nakano was able to show that ''Ingrid'' had been observed and provisionally designated several times during its lost period: as at the discovering Heidelberg Observatory in October 1957, possibly as at Goethe Link Observatory in April 1963, as at the Crimean Astrophysical Observatory in No ...
