204 Kallisto is a fairly typical, although sizeable Main belt asteroid. It is classified as an S-type asteroid. Like other asteroids of its type, it is light in colour. It was discovered by Johann Palisa on 8 October 1879, in Pola, and was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto.
Photometric measurements during 2009 produced a lightcurve that indicated a sidereal rotation period of 19.489±0.002 h with a variation amplitude of 0.18±0.02 magnitudes. This result conflicted with previous determinations of the period, so the latter were ruled out. [4]
81 Terpsichore is a large and very dark main-belt asteroid. It has most probably a very primitive carbonaceous composition. It was found by the prolific comet discoverer Ernst Tempel on September 30, 1864. It is named after Terpsichore, the Muse of dance in Greek mythology.
99 Dike is a quite large and dark main-belt asteroid. Dike was discovered by Alphonse Borrelly on May 28, 1868. It was his first asteroid discovery. This object is named after Dike, the Greek goddess of moral justice. Among the first hundred numbered minor planets, 99 Dike was considered anomalously faint for over a century. However, this was later found to be untrue.
112 Iphigenia is a fairly large and exceedingly dark main-belt asteroid. It is classified as a C-type asteroid, and therefore probably has a primitive carbonaceous composition. It was discovered by German-American astronomer C. H. F. Peters on September 19, 1870, and named after Iphigenia, a princess sacrificed by her father in Greek mythology. The orbital elements for 112 Iphigenia were published by German astronomer Friedrich Tietjen in 1871.
120 Lachesis is a large main-belt asteroid. It was discovered by French astronomer Alphonse Borrelly on April 10, 1872, and independently by German-American astronomer Christian Heinrich Friedrich Peters on April 11, 1872, then named after Lachesis, one of the Moirai, or Fates, in Greek mythology. A Lachesean occultation of a star occurred in 1999 and was confirmed visually by five observers and once photoelectrically, with the chords yielding an estimated elliptical cross-section of 184 × 144 km.
154 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.
157 Dejanira is a main belt asteroid that was discovered by Alphonse Borrelly on 1 December 1875, and named after the warlike princess Deianira in Greek mythology. The Dejanira family of asteroids is named after it.
200 Dynamene is a large dark main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on July 27, 1879, in Clinton, New York. The name derives from Dynamene, one of the fifty Nereids in Greek mythology. Based upon its spectrum, 200 Dynamene is classified as a C-type asteroid, indicating that it probably has a primitive composition similar to the carbonaceous chondrite meteorites. The spectra of the asteroid displays evidence of aqueous alteration.
207 Hedda is a sizeable Main belt asteroid. It is a C-type asteroid, meaning it is primitive in composition and dark in colour. This asteroid was discovered by Johann Palisa on October 17, 1879, in Pola and was named after Hedwig Winnecke, wife of astronomer Friedrich A. T. Winnecke.
217 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.
224 Oceana is an asteroid from the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 30 March 1882, in Vienna. It was named after the Pacific Ocean. Based upon its spectrum, it is classified as an M-type asteroid, but is not metallic.
240 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.
252 Clementina is a large main belt asteroid that was discovered by French astronomer Henri Joseph Anastase Perrotin on 11 October 1885 in Nice, France. The origin of the name is not known.
266 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.
285 Regina is a typical, although fairly large, Main belt asteroid. It was discovered by Auguste Charlois on 3 August 1889 in Nice, France. The asteroid is a suspected interloper in the Eucharis asteroid family.
309 Fraternitas is a typical Main belt asteroid. It was discovered by Johann Palisa on 6 April 1891 in Vienna. The asteroid name is Latin for 'fraternity'; it was so named in order to commemorate the 25th anniversary of the Maturitätsprüfung Fraternity.
331 Etheridgea is a large main belt asteroid. It was discovered by Auguste Charlois on 1 April 1892 in Nice. The meaning of the name is unknown. This asteroid is orbiting the Sun at a distance of 3.02 AU with a period of 5.26 years and an eccentricity (ovalness) of 0.10. The orbital plane is tilted at an angle of 6.05° to the plane of the ecliptic.
567 Eleutheria is a minor planet orbiting the Sun.
649 Josefa is a minor planet, specifically an asteroid, orbiting primarily in the asteroid belt. Photometric observations provide a rotation period of 10.481±0.001 h with a brightness variation of 0.33±0.04 in magnitude.
652 Jubilatrix is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered on 4 November 1907 by Austrian astronomer Johann Palisa, and was named in honor of the 60th anniversary of the reign of Franz Joseph. The asteroid is orbiting at a distance of 2.55 AU with a period of 4.08 yr and an eccentricity of 0.127. It is a member of the Maria dynamic family. Photometric observations provide a rotation period of 2.6627±0.0001 h with a brightness variation of 0.27±0.03 in magnitude.
690 Wratislavia is a minor planet orbiting the Sun. Wratislavia was discovered on October 16, 1909. IRAS data shows it is about 135 km in diameter.
