Herodias (minor planet designation: 546 Herodias) is a carbonaceous asteroid from the central regions of the asteroid belt, approximately 66 kilometers in diameter. It is an identified Eunomian interloper. It was named after the biblical character Herodias.
Lumen is a carbonaceous asteroid from the intermediate asteroid belt, approximately 130 kilometers in diameter. It is an identified Eunomian interloper.
Panopaea is a large main belt asteroid. Its orbit is close to those of the Eunomia asteroid family; however, Panopaea is a dark, primitive carbonaceous C-type asteroid in contrast to the S-type asteroids of the Eunomian asteroids. The spectra of the asteroid displays evidence of aqueous alteration. Photometric studies give a rotation period of 15.797 hours and an amplitude of 0.11±0.01 in magnitude. Previous studies that suggested the rotation period may be twice this amount were rejected based upon further observation.
Ampella is a Main belt asteroid that was discovered by Alphonse Borrelly on June 13, 1879. The name seems to be the feminine form of Ampelos, a satyr and good friend of Dionysus in Greek mythology. It could also derive from the Ampelose, a variety of hamadryad. It is an S-type asteroid.
Ludovica is a main belt asteroid.
389 Industria is a large background asteroid, approximately 79 kilometers in diameter, located in the central region of the asteroid belt. It was discovered on 8 March 1894, by French astronomer Auguste Charlois at the Nice Observatory. The stony S-type asteroid has a rotation period of 8.5 hours. It was named after the Latin word for "diligence".
460 Scania is a background asteroid and a slow rotator from the central regions of the asteroid belt. It was discovered by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory on 22 October 1900. The uncommon K-type asteroid has an exceptionally long rotation period of 164.1 hours and measures approximately 21 kilometers in diameter. It was named after the Swedish region of Scania, where a meeting was held by the Astronomische Gesellschaft in 1904.
Argentina is an asteroid that was discovered by Luigi Carnera on 20 February 1901. Its provisional name was 1901 GE. 469 Argentina has an estimated rotation period of 12.3 hours.
653 Berenike is a main-belt asteroid discovered on 27 November 1907 by Joel Hastings Metcalf at Taunton, Massachusetts. It is named after Berenice II of Egypt, after whom the constellation Coma Berenices is also named. The name may have been inspired by the asteroid's provisional designation 1907 BK.
756 Lilliana is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on 26 April 1908 from Taunton, Massachusetts. It rotates around its axis of rotation every 9.36 hours.
788 Hohensteina is a main-belt asteroid discovered on 4 April 1914 by Franz Kaiser at Heidelberg-Königstuhl State Observatory. Named for castle Hohenstein located in the Taunus mountains.
1675 Simonida, provisional designation 1938 FB, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 11 kilometers in diameter. Discovered by Milorad Protić in 1938, it was later named after the medieval Byzantine princess Simonida.
12714 Alkimos is a large Jupiter trojan from the Greek camp, approximately 54 kilometers in diameter. It was discovered on 15 April 1991, by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California. The dark Jovian asteroid has a rotation period of 28.5 hours. It was named from Greek mythology after Alcimus, son of Ares and companion of Achilles.
25000 Astrometria (provisional designation 1998 OW5) is a dark background asteroid from the outer regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 28 July 1998, by American astronomer Paul Comba at his Prescott Observatory in Arizona, United States. The asteroid was named in honor of the astronomical branch astrometry.
9344 Klopstock, provisional designation 1991 RB4, is a background asteroid from the inner regions of the asteroid belt. It was discovered on 12 September 1991, by German astronomers Freimut Börngen and Lutz Schmadel at the Karl Schwarzschild Observatory in Tautenburg, Germany. Poor observational data suggests that the asteroid is one of the darkest known objects with a diameter of approximately 17 kilometers (11 miles), while it is also an assumed stony asteroid with a much smaller diameter. It has a rotation period of 5.84 hours and was named after German poet Friedrich Gottlieb Klopstock.
4754 Panthoos is a Jupiter trojan from the Trojan camp, approximately 53 kilometers in diameter. It was discovered during the third Palomar–Leiden Trojan survey on 16 October 1977, by Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at the Palomar Observatory in California. It is likely spherical in shape and has a longer-than-average rotation period of 27.68 hours. The assumed C-type asteroid is one of the 80 largest Jupiter trojans. It was named after Panthous (Panthoos) from Greek mythology.
1345 Potomac, provisional designation 1908 CG, is a dark Hildian asteroid from the outermost regions of the asteroid belt, approximately 73 kilometers (45 mi) in diameter. It was discovered on 4 February 1908, by American astronomer Joel Metcalf at the Taunton Observatory in Massachusetts, United States. The X-type asteroid has a rotation period of 11.4 hours. It was named for the Potomac River on which Washington, D.C. is located.
1239 Queteleta, provisional designation 1932 CB, is a dark background asteroid from the central regions of the asteroid belt, approximately 17 kilometers in diameter. It was discovered on 4 February 1932, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. The asteroid was named after Adolphe Quetelet, a Belgian astronomer and mathematician.
2223 Sarpedon is a dark Jupiter trojan from the Trojan camp, approximately 90 kilometers in diameter. It was discovered on 4 October 1977, by astronomers at the Purple Mountain Observatory near Nanking, China. The D-type asteroid belongs to the 30 largest Jupiter trojans and has a rotation period of 22.7 hours. It was named after the Lycian hero Sarpedon from Greek mythology.
11351 Leucus is a mid-sized Jupiter trojan from the Greek camp, approximately 40 kilometers in diameter. It is a target of the Lucy mission, scheduled for a flyby in April 2028. The assumed D-type asteroid is an exceptionally slow rotator with a rotation period of 466 hours. It was discovered on 12 October 1997 by the Beijing Schmidt CCD Asteroid Program (SCAP) at Xinglong Station in the Chinese province of Hebei, and later named after the Achaean warrior Leucus from Greek mythology.
16974 Iphthime (; provisional designation 1998 WR21) is a Jupiter trojan and a binary system from the Greek camp, approximately 57 kilometers (35 miles) in diameter. It was discovered on 18 November 1998, by astronomers with the Lincoln Near-Earth Asteroid Research at the ETS Test Site in Socorro, New Mexico. The dark Jovian asteroid belongs to the 80 largest Jupiter trojans and has a notably slow rotation of 78.9 hours. It was named after Iphthime from Greek mythology. The discovery of its companion by Hubble Space Telescope was announced in March 2016.
