646 Kastalia is a minor planet orbiting the Sun, not to be confused with the near-Earth asteroid 4769 Castalia.
4769 Castalia is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometers in diameter and was the first asteroid to be modeled by radar imaging. It was discovered on 9 August 1989, by American astronomer Eleanor Helin (Caltech) on photographic plates taken at Palomar Observatory in California. It is named after Castalia, a nymph in Greek mythology. It is also a Mars- and Venus-crosser asteroid.
Comet Elst–Pizarro is a body that displays characteristics of both asteroids and comets, and is the prototype of active asteroids. Its orbit keeps it within the asteroid belt, yet it displayed a dust tail like a comet while near perihelion in 1996, 2001, and 2007.
199 Byblis is a medium-sized main belt asteroid.
Coelestina is a typical main belt asteroid.
Huberta is a large asteroid orbiting near the outer edge of the Main belt. It is dark and rich in carbon.
Dresda is a typical Main belt asteroid. It belongs to the Koronis family of asteroids.
343 Ostara is a background asteroid from the inner region of the asteroid belt. It was discovered by German astronomer Max Wolf at the Heidelberg Observatory on 15 November 1892.
361 Bononia is a very large, resonant Hilda asteroid located in the outermost region of the asteroid belt. It is classified as a D-type asteroid and is probably composed of organic rich silicates, carbon and anhydrous silicates. It was discovered by Auguste Charlois on 11 March 1893, in Nice, and assigned the prov. designations A893 EF and 1893 P.
394 Arduina is an asteroid from the central regions of the asteroid belt. It was discovered by A. Borrelly on 19 November 1894 in Marseilles.
Nassovia is a minor planet orbiting the Sun. It is a member of the Koronis family of asteroids.
621 Werdandi is a Themistian asteroid.
623 Chimaera is a minor planet, specifically an asteroid orbiting in the asteroid belt.
625 Xenia is a minor planet orbiting the Sun. It was discovered by August Kopff in Heidelberg, Germany, on 11 February 1907. The name may have been inspired by the asteroid's provisional designation 1907 XN.
633 Zelima is a minor planet orbiting the Sun in the asteroid belt with a magnitude of 10.7. The name may have been inspired by the asteroid's provisional designation 1907 ZM.
662 Newtonia is a minor planet, specifically an asteroid orbiting mostly in the asteroid belt.
668 Dora is an asteroid orbiting in the asteroid belt located roughly between the orbits of the planets Mars and Jupiter. The name may have been inspired by the asteroid's provisional designation 1908 DO.
768 Struveana is a minor planet orbiting the Sun. The asteroid was named jointly in honor of Baltic German astronomers Friedrich Georg Wilhelm von Struve, Otto Wilhelm von Struve and Karl Hermann Struve.
818 Kapteynia is a minor planet orbiting the Sun. This asteroid is named for the Dutch astronomer Jacobus Kapteyn.
852 Wladilena is a Phocaea asteroid from the inner region of the asteroid belt. It is named after the Russian Communist leader Vladimir Lenin.
6144 Kondojiro (1994 EQ3) is an asteroid discovered on March 14, 1994 by Kin Endate and Kazuro Watanabe at the Kitami Observatory in eastern Hokkaidō, Japan. It is named after Jiro Kondo, a Japanese Egyptologist and professor of archaeology at Waseda University.
