223 Rosa is a large Themistian asteroid. It is classified as a combination of C-type and P-type asteroids, so it is probably composed of carbonaceous material rich in water ice. It was discovered by Johann Palisa on 9 March 1882, in Vienna. The origin of the name is not known.
Photometric observations made in 2011–2012 at the Organ Mesa Observatory in Las Cruces, New Mexico, produced a light curve with a period of 20.283 ± 0.002 hours and a brightness variation of 0.13 ± 0.02 in magnitude. The curve has two asymmetrical maxima and minima per 20.283-hour cycle. [4]
A flyby of Rosa by the JUICE spacecraft, which is planned to pass through the asteroid belt twice, was proposed to occur on 15 October 2029. [2] However, the mission team ultimately decided against the proposed flyby to maximize fuel for the primary mission. [5]
108 Hecuba is a fairly large and bright main-belt asteroid. It was discovered by Karl Theodor Robert Luther on 2 April 1869, and named after Hecuba, wife of King Priam in the legends of the Trojan War in Greek Mythology. This object is orbiting the Sun with a period of 5.83 years and an eccentricity of 0.06. It became the first asteroid discovered to orbit near a 2:1 mean-motion resonance with the planet Jupiter, and is the namesake of the Hecuba group of asteroids.
176 Iduna is a large main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on October 14, 1877, in Clinton, New York. It is named after Sällskapet Idun, a club in Stockholm that hosted an astronomical conference; Idun is also a Norse goddess. A G-type asteroid, it has a composition similar to that of the largest main-belt asteroid, 1 Ceres.
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.
273 Atropos is a typical Main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 8 March 1888 in Vienna.
400 Ducrosa is a typical Main belt asteroid. It was discovered by Auguste Charlois on 15 March 1895 in Nice.
568 Cheruskia is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by German astronomer Paul Götz on 26 July 1905 from Heidelberg.
573 Recha is a minor planet, specifically an asteroid orbiting in the asteroid belt between Mars and Jupiter. The asteroid, discovered by German astronomer Max Wolf on September 19, 1905, was named after a character in Gotthold Ephraim Lessing's play Nathan the Wise and may have been inspired by the asteroid's provisional designation 1905 RC.
585 Bilkis is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered by German astronomer August Kopff in 1906 February and was given the Koran name for the Queen of Sheba. Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado in 2006–7 were used to build a light curve for this object. The asteroid displayed a rotation period of 8.5742 ± 0.0005 hours and a brightness variation of 0.40 ± 0.02 in magnitude.
605 Juvisia is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered 27 August 1906 in Heidelberg by German astronomer Max Wolf. It was named after the commune Juvisy-sur-Orge, France, where French astronomer Camille Flammarion had his observatory.
620 Drakonia is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered October 26, 1906, in Taunton, Massachusetts, by American astronomer Joel Hastings Metcalf and given the preliminary designation 1906 WE. It may have been named for Drake University.
630 Euphemia is a mid-sized Eunomian asteroid.
639 Latona is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered by German astronomer Karl Lohnert on July 19, 1907, at Heidelberg.
687 Tinette is a minor planet, specifically an asteroid orbiting primarily in the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 16 August 1909 from Vienna and was given the preliminary designation 1909 HG.
1583 Antilochus is a large Jupiter trojan from the Greek camp, approximately 108 kilometers in diameter. It was discovered on 19 September 1950, by Belgian astronomer Sylvain Arend at Uccle Observatory in Belgium, and later named after the hero Antilochus from Greek mythology. The dark D-type asteroid belongs to the 20 largest Jupiter trojans and has a rotation period of 15.9 hours. It forms an asteroid pair with 3801 Thrasymedes.
2920 Automedon is a large Jupiter trojan from the Greek camp, approximately 110 kilometers in diameter. It was discovered by American astronomer Edward Bowell at the Anderson Mesa station of the Lowell Observatory on 3 May 1981. The dark D-type asteroid has a rotation period of 10.22 hours and belongs to the 30 largest Jupiter trojans. It was named after the ancient Greek hero Automedon, the charioteer of Achilles.
1817 Katanga, provisional designation 1939 MB, is a stony Phocaea asteroid in from the inner regions of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 20 June 1939, by English-born South African astronomer Cyril Jackson at Johannesburg Observatory in South Africa. It is named for the Katanga Province.
5641 McCleese, provisional designation 1990 DJ, is a rare-type Hungaria asteroid and slow rotator, classified as Mars-crosser from the innermost regions of the asteroid belt, approximately 4 kilometers in diameter.
1269 Rollandia, provisional designation 1930 SH, is a dark Hildian asteroid from the outermost region of the asteroid belt, approximately 105 kilometers (65 mi) in diameter. It was discovered on 20 September 1930, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. The asteroid was named after French writer Romain Rolland. The D-type asteroid has a rotation period of 17.4 hours. It was one of the last 100-kilometer sized asteroids discovered in the main belt.
8373 Stephengould is an outer main-belt binary asteroid discovered on 1 January 1992 by Carolyn S. Shoemaker and Eugene Merle Shoemaker at Palomar Observatory. The asteroid was named after the Harvard paleontologist Stephen Jay Gould. The asteroid has a very high inclination, having the second highest inclination of any of the first 10,000 discovered asteroids in the asteroid belt, after 2938 Hopi.
3401 Vanphilos, provisional designation 1981 PA, is a stony, eccentric asteroid and sizeable Mars-crosser, approximately 7 kilometers in diameter. It was discovered on 1 August 1981, by and at Harvard's Oak Ridge Observatory in Massachusetts, United States.
