723 Hammonia
723 Hammonia is a minor planet orbiting the Sun. It was discovered in 1911 and is named after the city of Hamburg. Although the name alludes to Hamburg it was discovered in Vienna. (Vienna is the capital of Austria) The asteroid was discovered by the noted and prolific astronomer Johann Palisa. He worked from Pola early in his career and later from Vienna observatories. The same night he discovered Hammonia, he also discovered 724 Hapag and 725 Amanda. He discovered dozens and dozens of asteroids between 1874 and 1923, ranging from 136 Austria to 1073 Gellivara. As seen from a certain area on Earth, 723 Hammonia occulted the star 3UC149-190572 on June 3, 2013. In 2014 it was noted to have a high-albedo and amorphous Mg pyroxenes was suggested as a possible reason for this.

724 Hapag
{{beltasteroid-stub ...
724 Hapag is a minor planet orbiting the Sun in the asteroid belt that was found by Austrian astronomer Johann Palisa in 1911 and named after the German shipping company Hamburg America Line. It was assigned a provisional name of 1911 NC, then became a lost asteroid until it was rediscovered in 1988 as ' by Tsutomu Hioki and N. Kawasato at Okutama, Japan. Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico in 2011 gave a light curve with a period of 3.1305 ± 0.0001 hours and a brightness variation of 0.11 ± 0.01 in magnitude.

449 Hamburga
Hamburga (minor planet designation: 449 Hamburga) is a carbonaceous asteroid from the background population of the intermediate asteroid belt, approximately 75 kilometers in diameter. It was discovered by German astronomers Max Wolf and Friedrich Schwassmann at Heidelberg Observatory on 31 October 1899, and later named after the city of Hamburg in Germany. 449 was a proposed target for the 1980s-1990s space probe mission proposal CRAF. Description ''Hamburga'' is classified as a C-type asteroid and is probably composed of carbonaceous material. It is named for the city of Hamburg in Germany. The name was announced in 1901 during a festival held by the Mathematical Society of Hamburg. 449 Hamburga was identified as one of three asteroids that were likely to be a parent body for chondrites along with 304 Olga and 335 Roberta. All three asteroids were known to have low-albedo (not reflect as much light) and be close to "meteorite producing resonances". Chrondrites are the mo ...

1073 Gellivara
1073 Gellivara, provisional designation , is a dark Themistian asteroid, approximately in diameter, located in the outer regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 14 September 1923, and later named after the Swedish town of Gällivare. Orbit and classification ''Gellivara'' is a Themistian asteroid that belongs to the Themis family (), a very large family of carbonaceous asteroids, named after 24 Themis. It orbits the Sun in the outer asteroid belt at a distance of 2.6–3.8 AU once every 5 years and 8 months (2,079 days; semi-major axis of 3.19 AU). Its orbit has an eccentricity of 0.19 and an inclination of 2 ° with respect to the ecliptic. The body's observation arc begins at Vienna on 1 October 1923, two weeks after its official discovery observation.

136 Austria
Austria ( minor planet designation: 136 Austria) is a main-belt asteroid that was found by the prolific asteroid discoverer Johann Palisa on 18 March 1874, from the Austrian Naval Observatory in Pola, Istria. It was his first asteroid discovery and was given the Latin name of his homeland. Based upon its spectrum, it is classified as an M-type spectrum, although Clark et al. (1994) suggest it may be more like an S-type asteroid. It shows almost no absorption features in the near infrared, which may indicate an iron or enstatite chondrite surface composition. A weak hydration feature was detected in 2006. Photometric observations of this asteroid at the European Southern Observatory in 1981 gave a light curve with a period of 11.5 ± 0.1 hours and a brightness variation of 0.40 in magnitude Magnitude may refer to: Mathematics *Euclidean vector, a quantity defined by both its magnitude and its direction *Magnitude (mathematics), the relative size of an object *Norm (ma ...

725 Amanda ('' prov. designation:'' ''or'' ) is a dark background asteroid, approximately in diameter, that is located in the central regions of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 21 October 1911. The carbonaceous C-type asteroid (CSU/C0) has a short rotation period of 3.7 hours. It was named after Amanda Schorr, wife of German astronomer Richard Schorr (1867–1951). Orbit and classification ''Amanda'' 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 central asteroid belt at a distance of 2.0–3.1 AU once every 4 years and 2 months (1,507 days; semi-major axis of 2.57 AU). Its orbit has an eccentricity of 0.22 and an inclination of 4 ° with respect to the ecliptic.

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.

Vienna Observatory
The Vienna Observatory (german: Universitätssternwarte Wien) is an astronomical observatory in Vienna, Austria. It is part of the University of Vienna. The first observatory was built in 1753–1754 on the roof of one of the university buildings. A new observatory was built between 1874 and 1879, and was finally inaugurated by Emperor Franz Joseph I of Austria in 1883. The main dome houses a refractor with a diameter of and a focal length of built by the Grubb Telescope Company. At that time, it was the world's largest refracting telescope. Land for the new observatory was purchased in 1872, and was noted for having increased elevations (about 150 ft) above the city. Construction started in March 1874, and it was opened with new instruments in 1877. The overall design had various rooms and three main domes, one for the Grubb refractor and then two smaller domes, and some terraces. At this time there were larger aperture reflecting telescopes, and the main technologies o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilometre
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre ...
