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 reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

9321 Alexkonopliv
9321 Alexkonopliv, provisional designation ', is a carbonaceous background asteroid from the outer region of the asteroid belt, approximately 11 kilometers in diameter. The asteroid was discovered on 5 January 1989, by Japanese astronomer Takuo Kojima at the YGCO Chiyoda Station, Japan. It was named for JPL-scientist Alex Konopliv. Orbit and classification ''Alexkonopliv'' is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer asteroid belt at a distance of 2.3–3.9 AU once every 5 years and 6 months (2,004 days). Its orbit has an eccentricity of 0.26 and an inclination of 4 ° with respect to the ecliptic. In November 1977, it was first identified as at the Purple Mountain Observatory, China, extending the body's observation arc by 12 years prior to its official discovery observation at Chiyoda Station. Naming This minor planet was named after JPL-scientist Alex Konopliv (born 1960), an internationally recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
7517 Alisondoane
7517 Alisondoane ( ''prov. designation'': ) is a dark background asteroid from the inner regions of the asteroid belt. It was discovered on 3 January 1989, by Japanese amateur astronomer Takuo Kojima at the YGCO Chiyoda Station in the northern Kantō region of Japan. The carbonaceous C-type asteroid has a rotation period of 9.7 hours and measures approximately in diameter. It was named after Alison Doane (1958–2017), curator of astronomical photographs at the Harvard College Observatory. Orbit and classification ''Alisondoane'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 10 months (1,397 days). Its orbit has an eccentricity of 0.26 and an inclination of 6 ° with respect to the ecliptic. Naming This minor planet was named in honor of Alison Doane (1958–2017), c ...

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
