Poul Jensen (astronomer)
Poul B. Jensen is a Danish astronomer and a discoverer of 98 minor planets while working at Brorfelde Observatory. Between 1967 and 1969 he assisted in positional observations with the observatory's 7" transit circle. He is also a co-discoverer (with Carolyn S. Shoemaker) of the Comet Jensen-Shoemaker (1987g1). , he was still publishing in the ''Minor Planet Circulars''. On 22 July 1994, the main-belt asteroid 5900 Jensen was named by his colleges Karl Augustesen and Hans Jørn Fogh Olsen in his and his wife's honor ().

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.

__NOTOC__ Year 445 ( CDXLV) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valentinianus and Nomus (or, less frequently, year 1198 ''Ab urbe condita''). The denomination 445 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Europe * Emperor Valentinian III issues an imperial edict against Manichaeism. Heavy penalties are decreed against those who do not denounce the religion, and retain Manichaean books. * Petronius Maximus, prominent aristocrat, is given the title of Patrician. He becomes the most honored of all non-imperial Romans, and political rival of Flavius Aetius. * Bleda, co-ruler of the Huns, dies in a hunting accident. He is possibly murdered at the instigation of his younger brother Attila, with whom he has ruled since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On t ...
