871 Amneris is a minor planet orbiting the Sun. It is the namesake of the Amneris family, a subgroup of the Flora family of Main Belt asteroids.
This asteroid was named after Amneris, a character in Giuseppe Verdi's Aida . [2]
228 Agathe is a stony main belt asteroid, about 9 kilometers in diameter. It was discovered by Johann Palisa on 19 August 1882 at Vienna Observatory, Austria. Photometric observations during 2003 showed a rotation period of 6.48 ± 0.01 hours with a brightness variation of 0.27 ± 0.03 in magnitude. An earlier study yielded results that are consistent with these estimates. Agathe is the lowest numbered asteroid to have an Earth-MOID as low as 0.657 AU (98.3 million km). On 23 August 2029 the asteroid will be 0.659 AU (98.6 million km) from Earth.
254 Augusta is a main-belt asteroid, discovered on 31 March 1886 by astronomer Johann Palisa at Vienna Observatory, Austria. The stony S-type asteroid measures about 12 kilometers in diameter. It is the first-numbered member of the Augusta family, after which the small Asteroid family and subgroup of the main-belt has been named. Augusta was named after the German–Austrian writer Auguste von Littrow (1819–1890), widow of astronomer Carl Ludwig von Littrow, who was a former director of the Vienna Observatory.
258 Tyche is a relatively large main belt asteroid discovered by Robert Luther at Düsseldorf-Bilk Observatory on 4 May 1886. The stony S-type asteroid measures about 65 kilometers in diameter and has a perihelion of 2.1 AU.
320 Katharina is a small Main belt asteroid orbiting in the Eos family of asteroids, including 513 Centesima and 221 Eos. It was discovered by Johann Palisa on 11 October 1891 in Vienna. It is named after the discoverer's mother.
326 Tamara is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material. It is the largest member and namesake of the Tamara Family, a 264 million year-old sub-family of the collisional Phocaea family.
411 Xanthe is an asteroid from the outer regions of the asteroid belt, approximately 77 kilometers in diameter. It was discovered by French astronomer Auguste Charlois at Nice Observatory on 7 January 1896. The asteroid was named after Xanthe, an Oceanid or sea nymph, and one of the many Titan daughters of Oceanus and Tethys from Greek mythology.
421 Zähringia, provisional designation 1896 CZ, is a stony asteroid from the intermediate asteroid belt, approximately 14 kilometers in diameter. It was discovered on 7 September 1896, by astronomer Max Wolf at Heidelberg Observatory in Germany. The asteroid was named for the House of Zähringen, a medieval noble family that ruled parts of Swabia and Switzerland.
425 Cornelia is a large Main belt asteroid. It was discovered by Auguste Charlois on 28 December 1896 in Nice. It is named after Cornelia Africana.
459 Signe, provisional designation 1900 FM, is a stony asteroid from the background population of the intermediate asteroid belt, approximately 26 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg-Königstuhl State Observatory on 22 October 1900. The asteroid was presumably named after Signy, a character of the Scandinavian Völsunga saga and Norse mythology. Signy is the daughter of Völsung and sister of Sigmund.
542 Susanna is a minor planet orbiting the Sun.
610 Valeska is a minor planet, specifically an asteroid, orbiting primarily in the asteroid belt. Discovered in 1906 by Max Wolf. The origin of the name is unknown, but it may be related to the provisional designation 1906 VK. In Slavic origin, it also means Glorious ruler. Photometric observations provide a rotation period of 4.9047±0.0002 h with a brightness variation of 0.17±0.03 in magnitude.
642 Clara is a minor planet orbiting the Sun. Discovered by Max Wolf in 1907, it is named after one of the housekeepers in Wolf's household.
745 Mauritia is a dark background asteroid from the outer regions of the asteroid belt, approximately 24 kilometers in diameter. It was discovered on 1 March 1913, by German astronomer Franz Kaiser at the Heidelberg-Königstuhl State Observatory in Germany. The presumed carbonaceous C-type asteroid has a rotation period of 9.9 hours. It was named after Saint Maurice, patron of the Saint Mauritius church in the city of Wiesbaden, where the discoverer was born.
770 Bali is a minor planet orbiting the Sun. It is a member of the Flora family. It was discovered on 31 October 1913, by German astronomer Adam Massinger at the Heidelberg Observatory in southwest Germany. The asteroid was probably named after the Indonesian island of Bali, as the discoverer had named a couple other asteroids after places in Indonesia. The alternative hypothesis is that it was named after Bali, king of the Daityas in Hindu mythology.
820 Adriana, provisional designation 1916 ZB, is an exceptionally dark asteroid from the outer region of the asteroid belt, about 59 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory in southern Germany, on 30 March 1916.
837 Schwarzschilda, provisional designation 1916 AG, is a low-eccentric, well-observed asteroid from the asteroid belt, orbiting the Sun with a period of 3.48 years at a distance of 2.21–2.39 AU. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 23 September 1916.
858 El Djezaïr is a stony asteroid from the asteroid belt, about 24 kilometers in diameter. It was discovered on May 26, 1916, by French astronomer Frédéric Sy at the Algiers Observatory in Algeria, North Africa, and given the provisional designation 1916 a.
2981 Chagall, provisionally designated 1981 EE20, is a Themistian asteroid from the asteroid belt, discovered on 2 March 1981 by American astronomer Schelte Bus at Siding Spring Observatory in New South Wales, Australia.
2661 Bydžovský, provisional designation 1982 FC1, is an asteroid from the outer region of the asteroid belt, approximately 30 kilometers in diameter. It was discovered on 23 March 1982, by Czech astronomer Zdeňka Vávrová at the South Bohemian Kleť Observatory in the Czech Republic. The asteroid was named after mathematician Bohumil Bydžovský.
655 Briseïs is a minor planet orbiting the Sun.
