    Aurelia (minor planet designation: 419 Aurelia) is a main-belt asteroid that was discovered by German astronomer Max Wolf on September 7, 1896, in Heidelberg. It is classified as an F-type asteroid.

    Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave a "somewhat irregular" light curve with a period of 16.784 ± 0.001 hours and a brightness variation of 0.07 ± 0.01 in magnitude. When allowing for varying aspect angles and changes in mean motion, this result is consistent with past studies. [4]

    Circe, minor planet designation 34 Circe, is a large, very dark main-belt asteroid. It was discovered by French astronomer J. Chacornac on April 6, 1855, and named after Circe, the bewitching queen of Aeaea island in Greek mythology.

    Galatea is a large C-type main-belt asteroid. Its carbonaceous surface is very dark in color with an albedo of just 0.034. Galatea was found by the prolific comet discoverer Ernst Tempel on August 29, 1862, in Marseilles, France. It was his third asteroid discovery. It is named after one of the two Galateas in Greek mythology. A stellar occultation by Galatea was observed on September 8, 1987. The name Galatea has also been given to one of Neptune's satellites.

    Freia is a very large main-belt asteroid. It orbits in the outer part of the asteroid belt and is classified as a Cybele asteroid. Its composition is very primitive and it is extremely dark in color. Freia was discovered by the astronomer Heinrich d'Arrest on October 21, 1862, in Copenhagen, Denmark. It was his first and only asteroid discovery. It is named after the goddess Freyja in Norse mythology.

    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.

    Ianthe is a large main-belt asteroid, named for three figures in Greek mythology. It is very dark and is composed of carbonates. It was one of the numerous discoveries by C. H. F. Peters, who found it on April 18, 1868, from Clinton, New York.

    137 Meliboea is a large, dark main-belt asteroid that was discovered by Austrian astronomer J. Palisa at the Austrian Naval Observatory on 21 April 1874, the second of his many asteroid discoveries. It was later named after one of the three Meliboeas in Greek mythology. The largest body in the Meliboea family of asteroids that share similar orbital elements, only 791 Ani approaches its size. It is classified as a C-type asteroid and may be composed of carbonaceous materials. The spectra of the asteroid displays evidence of aqueous alteration.

    Adria is a fairly large main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on 23 February 1875, at the Austrian Naval Observatory, and named after the Adriatic Sea, on the coast of which the discovery was made. This dark-coloured asteroid has probably a primitive carbonaceous chondritic composition.

    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 October 18, 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.
