26 Proserpina is a main-belt asteroid discovered by German astronomer R. Luther on May 5, 1853. It is named after the Roman goddess Proserpina, the daughter of Ceres and the Queen of the Underworld. Another main-belt asteroid, 399 Persephone, discovered in 1895, is named after her Greek counterpart. Its historical symbol was a star inside a pomegranate; it is in the pipeline for Unicode 17.0 as U+1CECD ( ). [7] [8]
This object is orbiting the Sun with a period of 4.33 years. It has a cross-section size of around 90 km and a stony (S-type) composition. Photometric observations of this asteroid have produced discrepant estimates of the rotation period. A period of 12.13 hours was reported in 1979, followed by 10.6 hours in 1981 and 6.67 hours in 2001. Observations made in 2007 at the Oakley Observatory in Terre Haute, Indiana produced a light curve with a period of 13.06 ± 0.03 hours and a brightness variation of 0.21 ± 0.01 in magnitude. [9] This was refined by a 2008 study, giving a period of 13.110 ± 0.001 hours. [10]
11 Parthenope is a large, bright main-belt asteroid.
13 Egeria is a large main-belt G-type asteroid. It was discovered by Annibale de Gasparis on November 2, 1850. Egeria was named by Urbain Le Verrier, whose computations led to the discovery of Neptune, after the mythological nymph Egeria of Aricia, Italy, the wife of Numa Pompilius, second king of Rome.
14 Irene is a large main-belt asteroid, discovered by the English astronomer John Russell Hind on May 19, 1851. It is orbiting the Sun at a distance of 2.585 AU with a period of 4.16 yr and an eccentricity of 0.168. The orbital plane is tilted at an angle of 9.1° to the plane of the ecliptic.
18 Melpomene is a large, bright main-belt asteroid that was discovered by J. R. Hind on 24 June 1852, and named after Melpomenē, the Muse of tragedy in Greek mythology. Its historical symbol was a dagger over a star; it is in the pipeline for Unicode 17.0 as U+1CECB .
28 Bellona is a large main-belt asteroid. It was discovered by German astronomer R. Luther on March 1, 1854, and named after Bellōna, the Roman goddess of war; the name was chosen to mark the beginning of the Crimean War. Its historical symbol was Bellona's whip and spear; it is in the pipeline for Unicode 17.0 as U+1CECE .
35 Leukothea is a large, dark asteroid from the asteroid belt. It was discovered by German astronomer Karl Theodor Robert Luther on April 19, 1855, and named after Leukothea, a sea goddess in Greek mythology. Its historical symbol was a pharos ; it is in the pipeline for Unicode 17.0 as U+1CED0 .
37 Fides is a large main-belt asteroid. It was discovered by German astronomer Karl Theodor Robert Luther on October 5, 1855, and named after Fides, the Roman goddess of loyalty. Fides was the last of the main-belt asteroids to be assigned an iconic symbol, a Latin cross U+271D ✝. 37 Fides is also a S-type asteroid in the Tholen classification system.
57 Mnemosyne is a large main belt asteroid. It is a stony S-type asteroid in composition. This object was discovered by Robert Luther on 22 September 1859 in Düsseldorf. Its name was chosen by Martin Hoek, the director of the Utrecht Observatory, in reference to Mnemosyne, a Titaness in Greek mythology.
143 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.
159 Aemilia is a large main-belt asteroid. Aemilia was discovered by the French brothers Paul Henry and Prosper Henry on January 26, 1876. The credit for this discovery was given to Paul. It is probably named after the Via Aemilia, a Roman road in Italy that runs from Piacenza to Rimini.
242 Kriemhild is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 22 September 1884 in Vienna and was named after Kriemhild, a mythological Germanic princess, by Moriz von Kuffner, a Viennese industrialist and sponsor of astronomy.
340 Eduarda is a main belt asteroid that was discovered by German astronomer Max Wolf on 25 September 1892 in Heidelberg. It was named after German banker and amateur astronomer Heinrich Eduard von Lade.
381 Myrrha is a main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 10, 1894, in Nice. It has been classified as a C-type asteroid and is most likely composed of carbonaceous material.
536 Merapi is a main belt asteroid orbiting the Sun. It was discovered by American astronomer George Henry Peters on May 11, 1904, from Washington, D.C.
563 Suleika is a minor planet orbiting the Sun. Previously designated as 1905 QK, it was discovered by German astronomer Paul Götz on 6 April 1905 from Heidelberg, Germany.
799 Gudula is a minor planet orbiting the Sun discovered by German astronomer Karl Wilhelm Reinmuth on 9 March 1915 at the Heidelberg observatory.
1046 Edwin, provisional designation 1924 UA, is a background asteroid from the outer regions of the asteroid belt, approximately 30 kilometers kilometers in diameter. It was discovered on 1 December 1924, by Belgian–American astronomer George Van Biesbroeck at the Yerkes Observatory in Wisconsin, United States, who named it after his son, Edwin Van Biesbroeck. The potentially metallic asteroid has a short rotation period of 5.29 hours.
4175 Billbaum, provisional designation 1985 GX, is a background asteroid from the central regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 15 April 1985, by American astronomer Edward Bowell at the Anderson Mesa Station of the Lowell Observatory near Flagstaff, Arizona. The uncommon L-type asteroid has a short rotation period of 2.73 hours and was named for American astronomer William A. Baum.
1985 Hopmann is a dark background asteroid in the outer regions of the asteroid belt. It was discovered on 13 January 1929, by astronomer Karl Reinmuth at Landessternwarte Heidelberg-Königstuhl in southern Germany. The asteroid has a rotation period of 17.5 hours and measures approximately 36 kilometers in diameter. It was later named after German astronomer Josef Hopmann (1890–1975).
2903 Zhuhai, provisional designation 1981 UV9, is a stony background or Marian asteroid from the central regions of the asteroid belt, approximately 14 kilometers (8.7 miles) in diameter. It was discovered on 23 October 1981, by astronomers at Purple Mountain Observatory near Nanking, China. The S-type asteroid has a rotation period of 5.26 hours.
