172 Baucis is a large main belt asteroid that was discovered by French astronomer Alphonse Borrelly on February 5, 1877, and named after a fictional character in the Greek legend of Baucis and Philemon. The adjectival form of the name is Baucidian. It is classified as an S-type asteroid based upon its spectrum.
Photometric observations of this asteroid from the southern hemisphere during 2003 gave a light curve that indicated a slow synodic rotation period of 27.417 ± 0.013 hours and a brightness variation of 0.25 in magnitude. [3]
Polarimetric study of this asteroid reveals anomalous properties that suggests the regolith consists of a mixture of low and high albedo material. This may have been caused by fragmentation of an asteroid substrate with the spectral properties of CO3/CV3 carbonaceous chondrites. [4]
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.
118 Peitho is a main-belt asteroid. It is probably an S-type asteroid, suggesting a siliceous mineralogy. It was discovered by R. Luther on March 15, 1872, and named after one of the two Peithos in Greek mythology. There have been two observed Peithoan occultations of a dim star: one was in 2000 and the other in 2003.
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.
122 Gerda is a fairly large outer main-belt asteroid that was discovered by German-American astronomer C. H. F. Peters on July 31, 1872, and named after Gerðr, the wife of the god Freyr in Norse mythology. Based upon its spectrum, this is classified as an S-type asteroid. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter.
168 Sibylla is a large main-belt asteroid, discovered by Canadian-American astronomer J. C. Watson on September 28, 1876. It was most likely named for the Sibyls, referring to the Ancient Greek female oracles. Based upon its spectrum this object is classified as a C-type asteroid, which indicates it is very dark and composed of primitive carbonaceous materials. 168 Sibylla is a Cybele asteroid, orbiting beyond most of the main-belt asteroids.
181 Eucharis is a large, slowly rotating main-belt asteroid that was discovered by French astronomer Pablo Cottenot on February 2, 1878, from Marseille Observatory. It was his only asteroid discovery. This object was named after Eucharis, a nymph from the 17th-century novel Les Aventures de Télémaque.
214 Aschera is a Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on February 29, 1880, in Pola and was named after the Sidonian goddess Asherah.
234 Barbara is a main belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on August 12, 1883, in Clinton, New York. The object is orbiting the Sun with a semimajor axis of 2.385 AU, a period of 3.68 years, and an eccentricity of 0.25. The orbital plane is inclined by 15.37° to the plane of the ecliptic. It is classified as a stony S-type asteroid based upon its spectrum. The mean diameter of this object is estimated as 45.6 km. It has a rotation rate of 26.5 hours, or a little over a day. It is possibly named for Saint Barbara, patron saint of mathematicians.
236 Honoria is a large main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 26 April 1884 in Vienna. The asteroid was named after Honoria, granddaughter of the Roman Emperor Theodosius I, who started negotiations with Attila the Hun. It is classified as a stony S-type asteroid based upon its spectrum. 236 Honoria is orbiting close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 AU.
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 is orbiting 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.
402 Chloë is a large main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 21 March 1895 from Nice. This asteroid is orbiting the Sun at a distance of 2.56 AU with a period of 4.09 years and an eccentricity of 0.11. The orbital plane is inclined at an angle of 11.8° to the plane of the ecliptic.
466 Tisiphone is an asteroid which orbits among the Cybele family of asteroids.
673 Edda is a minor planet orbiting the Sun. It was discovered 20 September 1908 by the American astronomer Joel Hastings Metcalf, and was named for the Norse Edda literary works. The name may also have been inspired by the asteroid's provisional designation 1908 EA. This asteroid is orbiting at a distance of 2.81 AU with a period of 4.72 yr and an eccentricity of 0.012. The orbit is close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 AU.
678 Fredegundis is a minor planet orbiting the Sun. It was discovered 22 January 1909 from Heidelberg by German astronomer K. Wilhelm Lorenz, and was named after the French opera Frédégonde. This object is orbiting at a distance of 2.57 AU with a period of 4.13 years and an eccentricity (ovalness) of 0.22. The orbital plane is inclined at an angle of 6.1° to the plane of the ecliptic
679 Pax is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on January 28, 1909. It is named after Pax, a Roman goddess. It is orbiting the Sun with a period of 4.16 years and an eccentricity of 0.31.
740 Cantabia is a minor planet orbiting the Sun. It was discovered on 10 February 1913 at Winchester, Massachusetts by American amateur astronomer J. H. Metcalf. Cantabia is a contraction of Cantabrigia, Latin for Cambridge, named in honor of Cambridge, Massachusetts. It is orbiting at a distance of 3.05 AU with a period of 5.33 years and an eccentricity (ovalness) of 0.11. Between 2014 and 2021, 740 Cantabia has been observed to occult three stars.
753 Tiflis is a minor planet orbiting the Sun. It was discovered 30 April 1913 by the Georgian–Russian astronomer Grigory N. Neujmin at Simeiz Observatory and was named after Georgia's capital city Tiflis. The object is orbiting the Sun at a distance of 2.33 AU with a period of 3.55 years and an eccentricity (ovalness) of 0.22. The orbital plane is inclined by an angle of 10.1° to the plane of the ecliptic. In 1991, Ruth F. Wolfe included it as a member of the proposed Tiflis asteroid family.
761 Brendelia is a minor planet orbiting the Sun that was discovered by German astronomer Franz Kaiser on September 8, 1913, and named after Otto Rudolf Martin Brendel. It is orbiting at a distance of 2.8619 AU from the Sun with a period of 4.842 yr and an orbital eccentricity of 0.065297. The orbital plane is inclined at an angle of 2.16° to the plane of the ecliptic.
980 Anacostia is a minor planet orbiting the Sun that was discovered by American astronomer George Henry Peters on 21 November 1921. The name recognizes the Anacostia River and an historic neighborhood of the same name in the city of Washington D.C.
