Eichsfeldia (minor planet designation: 442 Eichsfeldia) is a large main belt asteroid that was discovered by German astronomers Max Wolf and A. Schwassmann on 15 February 1899 in Heidelberg. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.
Although Eichsfeldia has an orbit similar to the Vesta family asteroids, it was found to be an unrelated interloper on the basis of its non-matching spectral type.
Melete is a large and dark main belt asteroid. It is a rather unusual P-type asteroid, probably composed of organic rich silicates, carbon and anhydrous silicates, with possible internal water ice. The asteroid orbits the Sun with a period of 4.18 years.
Elpis, minor planet designation: 59 Elpis, is a large main belt asteroid that orbits the Sun with a period of 4.47 years. It is a C-type asteroid, meaning that it is very dark and carbonaceous in composition. In the Tholen scheme it has a classification of CP, while Bus and Binzen class it as type B.
Klotho is a fairly large main-belt asteroid. While it is an M-type, its radar albedo is too low to allow a nickel-iron composition. Klotho is similar to 21 Lutetia and 22 Kalliope in that all three are M-types of unknown composition. Klotho was found by Ernst Tempel on February 17, 1868. It was his fifth and final asteroid discovery. It is named after Klotho or Clotho, one of the three Moirai, or Fates, in Greek mythology.
Bertha is a main-belt asteroid. It was discovered by the French brothers Paul Henry and Prosper Henry on 4 November 1875, but the credit for the discovery was given to Prosper. It is probably named after Berthe Martin-Flammarion, sister of the astronomer Camille Flammarion.
Eudora is a large Main belt asteroid. It was discovered by French (Corsican) astronomer J. Coggia on August 30, 1880, in Marseilles, France. It was his fourth asteroid discovery and is named after Eudora, a Hyad in Greek mythology.
Eos is a large main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on January 18, 1882, in Vienna. In 1884, it was named after Eos, the Greek goddess of the dawn, to honour the opening of a new observatory that was hoped to bring about a new dawn for Viennese astronomy.
Vanadis is a fairly large main-belt asteroid with a diameter of around 100 km. It was discovered by A. Borrelly on August 27, 1884, in Marseilles and was named after Freyja (Vanadis), the Norse fertility goddess. The asteroid is orbiting the Sun at a distance of 2.67 AU with a period of 4.35 yr and an orbital eccentricity of 0.206. The orbital plane is inclined at an angle of 2.10° to the plane of the ecliptic.
Germania is a very large main-belt asteroid. It is classified as a B-type asteroid and is probably composed of dark, primitive carbonaceous material.
Liguria is a very large main-belt asteroid that was discovered by Auguste Charlois on January 21, 1893, in Nice. It is one of seven of Charlois's discoveries that was expressly named by the Astromomisches Rechen-Institut, and was named for the Italian region.
Myrrha is a main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 10, 1894, in Nice. It has been classified as a C-type asteroid and is most likely composed of carbonaceous material.
Arsinoë, minor planet designation 404 Arsinoë, is a large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
Edna is a large Main belt asteroid.
Patientia is approximately the 15th-largest asteroid in the asteroid belt with a diameter of 225 km. It was discovered by French astronomer Auguste Charlois on 4 December 1899, and assigned a provisional designation 1899 EY.
Papagena is an asteroid that was discovered by German astronomer Max Wolf on 7 June 1901. Its provisional name was 1901 GN.
Peraga is a minor planet orbiting the Sun that was discovered by German astronomer Paul Götz on January 8, 1905, from Heidelberg.
Semiramis is a minor planet orbiting the Sun within the main asteroid belt. Photometric observations at the Mark Evans Observatory during 2014 gave a rotation period of 5.0689 ± 0.0001 hours. This value is in close agreement with previous studies. The spectrum shows it to be a stony S(IV)-type asteroid.
Tekmessa is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on February 16, 1906. The name may have been inspired by the asteroid's provisional designation 1906 TK.
665 Sabine is a minor planet orbiting the Sun that was discovered by German astronomer Wilhelm Lorenz on July 22, 1908.
747 Winchester is an asteroid, a minor planet orbiting the Sun. It was discovered in 1913, and is named after the town in which it was discovered, Winchester, Massachusetts, in the USA.
804 Hispania is a minor planet orbiting the Sun. It was discovered from Barcelona (Spain) on 20 March 1915 by Josep Comas Solá (1868–1937), the first asteroid to be discovered by a Spaniard.
