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]
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.
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.
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.
Persephone is a main belt asteroid. It was discovered by German astronomer Max Wolf on 23 February 1895 in Heidelberg.
Arachne is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material. It was discovered on 13 October 1895, by German astronomer Max Wolf at Heidelberg Observatory.
Xanthe, minor planet designation 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.
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.

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.
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.
