Anton Thraen
Anton Karl Thraen (17 January 1843, Holungen, Province of Saxony – 18 February 1902, Dingelstädt) was a German astronomer and named two minor planets, 442 Eichsfeldia and 443 Photographica. Biography Thraen was born on 17 January 1843 in Holungen, in the Prussian Province of Saxony, where he attended the elementary school at that time. In 1863, he completed his schooling in Heiligenstadt and went to Westfälische Wilhelms-Universität Münster (1863–66), and the University of Paderborn (1866–68) and learned theology. Already in Munster, he also knew mathematical and astronomical lectures and helped at the observatory. From 1883 up to his death, he worked as a minister in Dingelstädt. Here, he organised charitable collections for the development of the hospital and the parish church. By night he often observed the sky with his telescope, particularly working on the orbits of comets and minor planets, publishing his results in international technical periodicals. De ...

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

People From Eichsfeld (district)
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Karl Schwarzschild Observatory
The Karl Schwarzschild Observatory (german: Karl-Schwarzschild-Observatorium) is a German astronomical observatory in Tautenburg near Jena, Thuringia. It was founded in 1960 as an affiliated institute of the former German Academy of Sciences at Berlin and named in honour of the astronomer and physicist Karl Schwarzschild (1873–1916). In 1992, the institute was re-established as Thuringian State Observatory (''Thüringer Landessternwarte'', TLS). The observatory has the largest telescope located in Germany, which is also the largest Schmidt camera in the world. Made by VEB Zeiss Jena (the branch of Carl Zeiss located in Jena in what was then East Germany), this instrument is known as (2m) Alfred Jensch Telescope: though its mirror is 2 metres in diameter, the telescope's aperture is 1.34 m. The observatory has observed several exoplanets and brown dwarfs, as around the stars HD 8673, 30 Arietis, 4 Ursae Majoris, and around HD 13189 on 5 April 2005. The observatory also host ...

4098 Thraen
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 the other hand, t ...
