Aethra is a metallic asteroid and Mars-crosser on an eccentric orbit from the asteroid belt. It measures approximately 40 kilometers in diameter.
Kallisto is a fairly typical, although sizeable Main belt asteroid. It is classified as an S-type asteroid. Like other asteroids of its type, it is light in colour. It was discovered by Johann Palisa on 8 October 1879, in Pola, and was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto.
Hedda is a sizeable Main belt asteroid. It is a C-type asteroid, meaning it is primitive in composition and dark in colour. This asteroid was discovered by Johann Palisa on October 17, 1879, in Pola and was named after Hedwig Winnecke, wife of astronomer Friedrich A. T. Winnecke.
Adrastea is a main belt asteroid. It was discovered by Johann Palisa on 18 August 1884 in Vienna, and was named after the Greek nymph Adrasteia. This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.11 years and an eccentricity (ovalness) of 0.23. The orbital plane is tilted at an angle of 6.17° to the plane of the ecliptic.
Valda is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 3 November 1886 in Vienna. The name was proposed by Bettina von Rothschild.
Regina is a typical, although fairly large, Main belt asteroid. It was discovered by Auguste Charlois on 3 August 1889 in Nice, France. The asteroid is a suspected interloper in the Eucharis asteroid family.
Thora is a 17 km Main belt asteroid with a potentially long 274-hour rotation period. It was discovered by Johann Palisa on 6 October 1890 in Vienna.
Eleutheria is a minor planet orbiting the Sun.
608 Adolfine is a minor planet, specifically an asteroid orbiting in the asteroid belt.
649 Josefa is a minor planet, specifically an asteroid, orbiting primarily in the asteroid belt. Photometric observations provide a rotation period of 10.481±0.001 h with a brightness variation of 0.33±0.04 in magnitude.
652 Jubilatrix is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered on 4 November 1907 by Austrian astronomer Johann Palisa, and was named in honor of the 60th anniversary of the reign of Franz Joseph. The asteroid is orbiting at a distance of 2.55 AU with a period of 4.08 yr and an eccentricity of 0.127. It is a member of the Maria dynamic family. Photometric observations provide a rotation period of 2.6627±0.0001 h with a brightness variation of 0.27±0.03 in magnitude.
701 Oriola is a main belt asteroid. This C-type asteroid shows possible broad absorption which may be explained by either magnesium-rich amorphous pyroxene or crystalline silicate. This likely accounts for the relatively high albedo as an outer-belt asteroid.
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.
972 Cohnia is a minor planet orbiting the Sun, one of several such in the asteroid belt. It was discovered on 18 January 1908 by a team in Heidelberg led by Max Wolf. In 2007, lightcurve data showed that Cohnia rotates every 18.472 ± 0.004 hours.
985 Rosina, provisional designation 1922 MO, is a stony asteroid and sizable Mars-crosser on an eccentric orbit from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 14 October 1922, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany. The asteroid's name is a common German female name, unrelated to the discoverer's contemporaries.
991 McDonalda is a Themistian asteroid. It was discovered by Otto Struve in 1922 at the Yerkes Observatory in Williams Bay, Wisconsin, United States. It is named after the McDonald Observatory, which Struve helped found in 1939.
992 Swasey is an asteroid, a minor planet orbiting the Sun. It was discovered by Otto Struve in 1922 at the Yerkes Observatory in Williams Bay, Wisconsin, United States. It is named after Ambrose Swasey of the Warner & Swasey Company, which built the 82-inch telescope named after Struve at McDonald Observatory.
2227 Otto Struve, provisional designation 1955 RX, is an asteroid from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter. The asteroid was discovered on 13 September 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. It was named after Russian astronomer Otto Struve.
1045 Michela, provisional designation 1924 TR, is an stony Massalian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers kilometers in diameter. It was discovered on 19 November 1924, by Belgian–American astronomer George Van Biesbroeck at the Yerkes Observatory in Williams Bay, Wisconsin, United States. The S-type asteroid was named after the discoverer's daughter, Micheline van Biesbroeck.
