681 Gorgo is a minor planet orbiting the Sun.
'Gorgo' is German for Gorgon. However, Ingrid van Houten-Groeneveld and Antonio Paluzie-Borrell suggest it may refer to "King of Salamine, in the 5th century B.C., who accompanied Xerxes in Greece." [2]
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.
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.
399 Persephone is a main belt asteroid. It was discovered by German astronomer Max Wolf on 23 February 1895 in Heidelberg.
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.
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.
612 Veronika is a minor planet orbiting the Sun. It was discovered on 8 October 1906 by August Kopff from Heidelberg. The reason for the name is unknown; asteroid etymologist Lutz D. Schmadel suspects that it may have been inspired by the letter code "VN" in its provisional designation, 1906 VN.
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.
805 Hormuthia is a minor planet orbiting the Sun. This asteroid follows an elliptical orbit through the main asteroid belt that reaches perihelion just outside the Kirkwood gap at 2.5 AU. Its estimated diameter is 73 km, and it is one of the 500 largest asteroids. 805 Hormuthia was discovered by Max Wolf in 1915, at the University of Heidelberg. The planet is named after Hormuth Kopff, the wife of astronomer August Kopff.
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.
853 Nansenia is a minor planet orbiting the Sun. It is named after the Norwegian polar explorer and Nobel Peace Prize laureate Fridtjof Nansen.
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.
902 Probitas is a minor planet orbiting the Sun. It was discovered by an Austrian astronomer Johann Palisa in Vienna on 3 September 1918.
953 Painleva is a minor planet orbiting the Sun. It was discovered on 29 April 1921 by the Russian astronomer Benjamin Jekhowsky. The planet was named in honor of the French statesman and mathematician Paul Painlevé.
1138 Attica, provisional designation 1929 WF, is an asteroid from the outer region of the asteroid belt, approximately 24 kilometers in diameter. It was discovered on 22 November 1929, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany. It was named after the Attica Province in Greece.
1818 Brahms, provisional designation 1939 PE, is an asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 15 August 1939, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. The asteroid was named after composer Johannes Brahms.
2311 El Leoncito, provisional designation 1974 TA1, is a dark and reddish asteroid from the outer region of the asteroid belt, approximately 53 kilometers in diameter. The asteroid was discovered by astronomers at Félix Aguilar Observatory at the Leoncito Astronomical Complex in Argentina on 10 October 1974. It was later named after the discovering site.
655 Briseïs is a minor planet orbiting the Sun.
