Ottilia (minor planet designation: 401 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.
The semi-major axis of the orbit of 401 Ottilia lies just outside the 2/1 Kirkwood gap, located at 3.27 AU. [2] 401 Ottilia is part of the Cybele asteroid group. [3]
Freia is a very large main-belt asteroid. It orbits in the outer part of the asteroid belt and is classified as a Cybele asteroid. Its composition is very primitive and it is extremely dark in color. Freia was discovered by the astronomer Heinrich d'Arrest on October 21, 1862, in Copenhagen, Denmark. It was his first and only asteroid discovery. It is named after the goddess Freyja in Norse mythology.
Nemesis is a large 180 km main-belt asteroid, of carbonaceous composition. It rotates rather slowly, taking about 78 hours to complete one rotation. Nemesis is the largest member of the Nemesian asteroid family bearing its name. It was discovered by J. C. Watson on 25 November 1872, and named after Nemesis, the goddess of retribution in Greek mythology.
168 Sibylla is a large main-belt asteroid, discovered by Canadian-American astronomer J. C. Watson on September 28, 1876. It was most likely named for the Sibyls, referring to the Ancient Greek female oracles. Based upon its spectrum this object is classified as a C-type asteroid, which indicates it is very dark and composed of primitive carbonaceous materials. 168 Sibylla is a Cybele asteroid, orbiting beyond most of the main-belt asteroids.
225 Henrietta is a very large outer main-belt asteroid. It was discovered by Austrian astronomer Johann Palisa on April 19, 1882, in Vienna and named after Henrietta, wife of astronomer Pierre J. C. Janssen. The asteroid is orbiting at a distance of 3.39 AU from the Sun with a period of 6.24 years and an eccentricity (ovalness) of 0.26. The orbital plane is inclined at an angle of 20.9° to the plane of the ecliptic. 225 Henrietta belongs to Cybele group of asteroids and is probably in a 4:7 orbital resonance with the planet Jupiter.
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.
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.
Tisiphone is an asteroid which orbits among the Cybele family of asteroids.
Laura is Main-belt asteroid discovered on 9 January 1901 by Max Wolf at Heidelberg. The semi-major axis of the orbit of 467 Laura lies just inside the 7/3 Kirkwood gap, located at 2.95 AU. It's named after the character Laura from Amilcare Ponchielli's opera La Gioconda.
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.
Deborah is a minor planet orbiting the Sun. It was discovered by Max Wolf on August 4, 1904. The semi-major axis of the orbit lies just inside the 5/2 Kirkwood gap, located at 2.824 AU. It was named after the biblical character Deborah.
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.
616 Elly is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
713 Luscinia is a large, main belt asteroid orbiting the Sun. It is a member of the Cybele asteroid group.
790 Pretoria is a minor planet orbiting the Sun that was discovered by English astronomer Harry Edwin Wood on January 16, 1912. It is a member of the Cybele group located beyond the core of the main belt and named after Pretoria, the capital city of South Africa.
875 Nymphe is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
903 Nealley is a minor planet orbiting the Sun. The semi-major axis of the orbit of 903 Nealley lies just inside the Hecuba gap, located at 3.27 AU.
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.
975 Perseverantia is a minor planet orbiting the Sun that was discovered by Austrian astronomer Johann Palisa on 27 March 1922.
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.
