Themis is one of the largest asteroids in the asteroid belt. It is also the largest member of the Themistian family. It was discovered by Annibale de Gasparis on 5 April 1853. It is named after Themis, the personification of natural law and divine order in Greek mythology.
Astraea is an asteroid in the asteroid belt. Its surface is highly reflective and its composition is probably a mixture of nickel–iron with silicates of magnesium and iron. It is an S-type asteroid in the Tholen classification system.
139 Juewa is a very large and dark main belt asteroid. It is probably composed of primitive carbonaceous material. It was the first asteroid discovered from China.
Davida is a large C-type asteroid. It is one of the largest asteroids; approximately tied for 7th place, to within measurement uncertainties, and the 5th or 6th most massive. It was discovered by R. S. Dugan in 1903. Davida is named after David Peck Todd, an astronomy professor at Amherst College.
Fortuna is one of the largest main-belt asteroids. It has a composition similar to 1 Ceres: a darkly colored surface that is heavily space-weathered with the composition of primitive organic compounds, including tholins.
Proserpina is a main-belt asteroid discovered by German astronomer R. Luther on May 5, 1853. It is named after the Roman goddess Proserpina, the daughter of Ceres and the Queen of the Underworld. Another main-belt asteroid, 399 Persephone, discovered in 1895, is named after her Greek counterpart.
Sappho is a large, S-type (stony) main-belt asteroid. It was discovered by English astronomer Norman Pogson on May 2, 1864, and is named after Sappho, the Archaic Greece poet. The asteroid is orbiting the Sun at a distance of 2.2957 AU with a period of 3.48 years and an eccentricity (ovalness) of 0.2. The orbital plane is inclined at an angle of 8.68° to the plane of the ecliptic.
Klio is a fairly large and very dark main-belt asteroid. It was discovered by R. Luther on August 25, 1865, and named after Clio, the Muse of history in Greek mythology. The name Clio had previously been suggested by the discoverer of 12 Victoria, and that is the name B. A. Gould, editor of the prestigious Astronomical Journal, adopted for that asteroid, because of the controversy over the name Victoria. An occultation by Klio over a dim star was observed on April 2, 1997.
Sylvia is one of the largest asteroids. It is the parent body of the Sylvia family and member of Cybele group located beyond the main asteroid belt. Sylvia was the first asteroid known to possess more than one moon.
Thisbe, minor planet designation 88 Thisbe, is the 13th largest main-belt asteroid. It was discovered by C. H. F. Peters on June 15, 1866, and named after Thisbe, heroine of a Roman fable. This asteroid is orbiting the Sun at a distance of 2.768 AU with a period of 4.60 years and an orbital eccentricity (ovalness) of 0.165. The orbital plane is inclined at an angle of 5.219° to the ecliptic.
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.
704 Interamnia is a large F-type asteroid. With a mean diameter of around 330 kilometres, it is the fifth-largest asteroid, after Ceres, Vesta, Pallas and Hygiea. Its mean distance from the Sun is 3.067 AU. It was discovered on 2 October 1910 by Vincenzo Cerulli, and named after the Latin name for Teramo, Italy, where Cerulli worked. Its mass is probably between fifth and tenth highest in the asteroid belt, with a mass estimated to be 1.2% of the mass of the entire asteroid belt. Observations by the Very Large Telescope's SPHERE imager in 2017–2019, combined with occultation results, indicate that the shape of Interamnia may be consistent with hydrostatic equilibrium for a body of its density with a rotational period of 7.6 hours. This suggests that Interamnia may have formed as an equilibrium body, and that impacts changed its rotational period after it fully solidified.
Aline is a fairly large main belt asteroid that was discovered by Johann Palisa on 17 May 1887 in Vienna and is thought to have been named after the daughter of astronomer Edmund Weiss. It is a dark C-type asteroid and is probably composed of primitive carbonaceous material. 266 Aline is orbiting close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 AU.
May is a large Main belt asteroid. It was discovered by Auguste Charlois on 28 November 1892 in Nice, and was named for the German author Karl May. This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.12 years and an eccentricity (ovalness) of 0.067. The orbital plane is inclined at an angle of 9.7° to the plane of the ecliptic. During its orbit, this asteroid has made close approaches to the dwarf planet Ceres. For example, in September 1984 the two were separated by 6.3 Gm (0.042 AU).
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.
Aquitania, provisional designation 1894 AZ, is a Postremian asteroid from the central regions of the asteroid belt, approximately 101 kilometers in diameter. Discovered by Fernand Courty at the Bordeaux Observatory in 1894, it was named for the French region of Aquitaine, the former province of Gallia Aquitania in the ancient Roman Empire.
Peraga is a minor planet orbiting the Sun that was discovered by German astronomer Paul Götz on January 8, 1905, from Heidelberg.
694 Ekard is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on November 7, 1909. The asteroid's name comes from the reverse spelling of Drake University in Des Moines, Iowa, where Seth Barnes Nicholson and his wife calculated its orbit.
765 Mattiaca is a minor planet, specifically an asteroid orbiting in the asteroid belt. Photometric observations made in 2011–2012 at the Organ Mesa Observatory in Las Cruces, New Mexico produced an irregular light curve and a period of 3.4640 ± 0.0001 hours with a brightness variation of 0.09 ± 0.01 in magnitude. Mattiacum was the Latin name for the city of Wiesbaden, Germany, birthplace of the discoverer.
