126 Velleda is a main-belt asteroid. It is probably a rather typical, albeit sizable, S-type asteroid. Named for Veleda, a priestess and prophet of the Germanic tribe of the Bructeri. It was discovered by Paul Henry on 5 November 1872, in Paris, France. It was his first credited discovery. He and his brother Prosper Henry discovered a total of 14 asteroids.
This body is orbiting the Sun with a period of 3.81 years and an eccentricity (ovalness) of 0.11. The orbital plane is inclined by 2.9° to the plane of the ecliptic. [2] It has a cross-section diameter of ~45 km. [3] This asteroid rotates once every 5.36 hours. During each rotation the brightness varies by 0.22 magnitudes. [4]
67 Asia is a large main belt asteroid. It was discovered by English astronomer N. R. Pogson on April 17, 1861, from the Madras Observatory. Pogson chose the name to refer both to Asia, a Titaness in Greek mythology, and to the continent of Asia, because the asteroid was the first to be discovered from that continent.
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 30 September 1864. It is named after Terpsichore, the Muse of dance in Greek mythology.
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.
150 Nuwa is a large main-belt asteroid with an orbital period of 5.15 years. It was discovered by Canadian-American astronomer James Craig Watson on 18 October 1875, and named after Nüwa, the Chinese creator goddess. This object is a candidate member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter. Based upon the spectrum it is classified as a C-type asteroid, which indicates that it is probably composed of primitive carbonaceous chondritic material and the surface is exceedingly dark.
161 Athor is an M-type Main belt asteroid that was discovered by James Craig Watson on April 19, 1876, at the Detroit Observatory and named after Hathor, an Egyptian fertility goddess. It is the namesake of a proposed Athor asteroid family, estimated to be ~3 billion years old.
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.
227 Philosophia is a large main-belt asteroid that was discovered by the French astronomer Paul-Pierre Henry on August 12, 1882, in Paris and named after the topic of philosophy. Based upon photometric observations, it has a synodic rotation period of 52.98 ± 0.01 with a brightness variation of 0.15 ± 0.02 in magnitude.
239 Adrastea is a main belt asteroid. It was discovered by Johann Palisa on 18 August 1884 in Vienna, and was named after the Greek nymph Adrasteia. This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.11 years and an eccentricity (ovalness) of 0.23. The orbital plane is tilted at an angle of 6.17° to the plane of the ecliptic.
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.
245 Vera is a large Main belt asteroid. It was discovered by N. R. Pogson on February 6, 1885, in Madras, and was named at the suggestion of his wife. The asteroid is orbiting the Sun at a distance of 3.11 AU with a period of 5.47 years and an eccentricity (ovalness) of 0.19. The orbital plane is tilted at an angle of 5.16° to the plane of the ecliptic. In 1890, Daniel Kirkwood noted that this asteroid shares similar orbital elements with 86 Semele and 106 Dione.
248 Lameia is a typical main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 5 June 1885 in Vienna and was named after the Lamia, a lover of Zeus in Ancient Greek mythology. 248 Lameia is orbiting the Sun with a period of 3.88 years and a low eccentricity (ovalness) of 0.067. The semimajor axis of 2.47 AU is slightly inward from the 3:1 Kirkwood Gap. Its orbital plane is inclined by 4° to the plane of the ecliptic.
300 Geraldina is a large Main belt asteroid. It was discovered by Auguste Charlois on October 3, 1890, in Nice. The origin of the name is unknown. It is orbiting the Sun at a distance of 3.21 AU with a period of 5.74 yr and an eccentricity (ovalness) of 0.057. The orbital plane is tilted at an angle of 0.73° to the plane of the ecliptic.
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.
310 Margarita is a typical Main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 16 May 1891 in Nice. The intended meaning of the asteroid's name is unknown. This minor planet is orbiting the Sun at a distance of 2.76 AU with a period of 4.592 years and an orbital eccentricity of 0.113. The orbital plane is inclined at an angle of 3.17° to the plane of the ecliptic.
328 Gudrun is a large main-belt asteroid. It was discovered by German astronomer Max Wolf on March 18, 1892, in Heidelberg. This minor planet is orbiting the Sun at a distance of 3.11 AU with a period of 5.486 yr and an orbital eccentricity of 0.106. The orbital plane is inclined at an angle of 16.1° to the plane of the ecliptic.
346 Hermentaria is a very large main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 25 November 1892, in Nice. It is probably named for the town of Herment in the region of Auvergne, France. The asteroid orbits the Sun with a period of 4.68 years and an eccentricity (ovalness) of 0.10. The orbital plane is inclined by 8.7° to the plane of the ecliptic.
400 Ducrosa is a typical Main belt asteroid. It was discovered by Auguste Charlois on 15 March 1895 in Nice, and named for It J. Ducros, a mechanic at the Nice Observatory. This minor planet is orbiting the Sun at a distance of 3.126 AU with a period of 5.527 yr and an orbital eccentricity of 0.117. The orbital plane is inclined at an angle of 10.5° to the plane of the ecliptic.
632 Pyrrha is a minor planet orbiting the Sun.
654 Zelinda is a minor planet orbiting the Sun that was discovered on 4 January 1908 by German astronomer August Kopff. It is orbiting the Sun at a distance of 2.297 AU with an orbital eccentricity of 0.23 and a period of 3.48 yr. The orbital plane is inclined at an angle of 18.1° to the plane of the ecliptic. On favorable oppositions, it can be as bright as magnitude 10.0, as observed on January 30, 2016.
758 Mancunia is a minor planet orbiting the Sun. It was discovered in 1912 from Johannesburg by H. E. Wood, a Mancunian. This object is orbiting at a distance of 3.19 AU with a period of 5.70 years and an eccentricity (ovalness) of 0.15. The orbital plane is inclined at an angle of 5.61° to the plane of the ecliptic.
