Cybele, minor planet designation 65 Cybele, is one of the largest asteroids in the Solar System. It is located in the outer asteroid belt. It is thought to be a remnant primordial body. It gives its name to the Cybele group of asteroids that orbit outward from the Sun from the 2:1 orbital resonance with Jupiter. The X-type asteroid has a relatively short rotation period of 6.0814 hours. It was discovered by Wilhelm Tempel in 1861, and named after Cybele, the earth goddess.
Astronomical symbols are abstract pictorial symbols used to represent astronomical objects, theoretical constructs and observational events in European astronomy. The earliest forms of these symbols appear in Greek papyrus texts of late antiquity. The Byzantine codices in which many Greek papyrus texts were preserved continued and extended the inventory of astronomical symbols. New symbols have been invented to represent many planets and minor planets discovered in the 18th to the 21st centuries.
1036 Ganymed, provisional designation 1924 TD, is a stony asteroid on a highly eccentric orbit, classified as a near-Earth object of the Amor group. It was discovered by German astronomer Walter Baade at the Bergedorf Observatory in Hamburg on 23 October 1924, and named after Ganymede from Greek mythology. With a diameter of approximately 35 kilometers, Ganymed is the largest of all near-Earth objects but does not cross Earth's orbit. The S-type asteroid has a rotation period of 10.3 hours. In October 2024, it is predicted to approach Earth at a distance of 56,000,000 km; 35,000,000 mi (0.374097 AU).
Iphigenia is a fairly large and exceedingly dark main-belt asteroid. It is classified as a C-type asteroid, and therefore probably has a primitive carbonaceous composition. It was discovered by German-American astronomer C. H. F. Peters on September 19, 1870, and named after Iphigenia, a princess sacrificed by her father in Greek mythology. The orbital elements for 112 Iphigenia were published by German astronomer Friedrich Tietjen in 1871.
Lomia is a large main-belt asteroid that has a nearly circular orbit; the orbital eccentricity is 0.029. It was discovered by French astronomer Alphonse Borrelly on September 12, 1871, from the Marseilles Observatory. The preliminary orbital elements were published in the following year by German astronomer Friedrich Tietjen. The reason for the name is uncertain, but Lutz D. Schmadel believes it is most likely a misspelling of Lamia, the female demon of Greek mythology.
Hertha is an asteroid from the inner region of the asteroid belt, approximately 77 kilometers in diameter. Discovered on 18 February 1874 by German–American astronomer Christian Peters at the Litchfield Observatory near Clinton, New York, it was named after the Teutonic and Scandinavian goddess of fertility, Hertha, also known as Nerthus. It orbits among the Nysa asteroid family, but its classification as a metallic M-type asteroid does not match the more common F-type asteroid for this family, suggesting that it may be an interloper. Spectroscopic analysis indicates the possible presence of hydrated silicates indicating that Hertha should possibly be reclassified from its present M-type to the proposed W-type.
Zelia is a main belt asteroid that was discovered by the brothers Paul Henry and Prosper Henry on September 28, 1876. Credit for this discovery was given to Prosper. Initial orbital elements for this asteroid were published in 1877 by American astronomer H. A. Howe.
229 Adelinda is a large, dark outer main-belt asteroid. It was discovered by Austrian astronomer Johann Palisa on August 22, 1882, in Vienna, and was named after Adelinda, the wife of fellow Austrian astronomer Edmund Weiss.
Huberta is a large asteroid orbiting near the outer edge of the Main belt. It is dark and rich in carbon.
Rosalia is a large Main belt asteroid. It was discovered by Auguste Charlois on 1 September 1891 in Nice.
Roxane is an asteroid from the asteroid belt approximately 19 km in diameter. It was discovered by Auguste Charlois from Nice on September 11, 1891. The name was chosen by F. Bidschof, an assistant at the Vienna Observatory, at Charlois' request; Bidschof chose to name it after Roxana, the wife of Alexander the Great, and at first used the spelling "Roxana".
Ottilia is a large main-belt asteroid. It was discovered by Max Wolf on March 16, 1895, in Heidelberg. It is named after the Germanic folkloric character Ottilia.
Bertholda is a very large main-belt asteroid. It was discovered by Max Wolf on September 7, 1896, in Heidelberg, Germany. The object is part of the Cybele asteroid group, and is classified as a P-type asteroid.
Ocllo is a large Mars-crossing asteroid. It was discovered by American astronomer DeLisle Stewart on August 14, 1901 and was assigned a provisional name of 1901 HN.
Helga, provisional designation 1904 NC is a large main belt asteroid. It was discovered in 1904 by Max Wolf in Heidelberg. Helga is notable for being the first such object to be shown to be in a stable but chaotic orbit in resonance with Jupiter, its Lyapunov time being relatively short, at 6,900 yr. Despite this, its orbit appears to be stable, as the eccentricity and precession rates are such that it avoids close encounters with Jupiter. It forms part of the Cybele asteroid group.
Friederike is a minor planet orbiting in the asteroid belt. It is a member of the Hygiea family of asteroids.
Kythera is a large, main belt asteroid orbiting the Sun. It was discovered in 1905 by German astronomer M. F. Wolf at Heidelberg, and was named after the Greek island of Kythira that is associated with Aphrodite. The object is a member of the Cybele asteroid group.
713 Luscinia is a large, main belt asteroid orbiting the Sun. It is a member of the Cybele asteroid group.
909 Ulla is a large and dark asteroid from the outermost regions of the asteroid belt, that measures approximately 116 kilometers in diameter. It is the parent body and namesake of the Ulla family, which belongs to the larger group of Cybele asteroids. It was discovered on 7 February 1919, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The X-type asteroid has a rotation period of 8.7 hours and a notably low value for its Jupiter Tisserand's parameter. It was named after Ulla Ahrens, daughter of a friend of the discoverer.
1467 Mashona, provisional designation 1938 OE, is a rare-type carbonaceous asteroid from the outer regions of the asteroid belt, approximately 100 kilometers in diameter, making it one of the top 200 largest asteroids currently known to exist. It was discovered on 30 July 1938, by South African astronomer Cyril Jackson at the Johannesburg Observatory in South Africa. It was later named after the native Shona people of Zimbabwe.
