Kythera (minor planet designation: 570 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. [3] The object is a member of the Cybele asteroid group. [4]
Bertha is a main-belt asteroid. It was discovered by the French brothers Paul Henry and Prosper Henry on 4 November 1875, but the credit for the discovery was given to Prosper. It is probably named after Berthe Martin-Flammarion, sister of the astronomer Camille Flammarion.
Irma is a fairly large and dark main belt asteroid. It was discovered by the French brothers Paul Henry and Prosper Henry on November 5, 1877. Paul was credited for this discovery. The meaning of the name Irma is unknown.
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.
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.
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.
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.
Eleutheria is a minor planet orbiting the Sun.
Reginhild is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on September 19, 1905. The name may have been inspired by the asteroid's provisional designation 1905 RD.
Rebekka is a minor planet orbiting the Sun, which was discovered on September 19, 1905, by a German astronomer Paul Götz in Heidelberg. It was named after a young lady from Heidelberg, and may have been inspired by the asteroid's provisional designation 1905 RB.
Rhea is a minor planet orbiting the Sun. It is named after Rhea, one of the Titans in Greek mythology. The name may have been inspired by the asteroid's provisional designation 1905 RH.
Sidonia is a minor planet orbiting the Sun that was discovered by the German astronomer August Kopff on November 3, 1905. It was named after a character in Christoph Willibald Gluck's opera Armide. The name may have been inspired by the asteroid's provisional designation 1905 SD.
713 Luscinia is a large, main belt asteroid orbiting the Sun. It is a member of the Cybele asteroid group.
721 Tabora is a minor planet orbiting the Sun. Tabora was named at a conference in Hamburg, Germany in 1913. The name was chosen because the conference was held aboard the passenger cargo liner Tabora of the Deutsche Ost-Afrika Linie. The asteroid is orbiting at a distance of 3.55 AU from the Sun with a period of 6.69 years and an eccentricity (ovalness) of 0.12. The orbital plane for is inclined at an angle of 8.3° to the plane of the ecliptic It is a member of the Cybele group in the outer belt, located close to the 7:4 and 16:9 orbital resonances with Jupiter.
880 Herba is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 22 July 1917 in Heidelberg.
Belopolskya, provisional designation 1923 OS, is a dark Cybele asteroid from the outermost region of the asteroid belt, approximately 75 kilometers (47 mi) in diameter. It was named for Russian astrophysicist Aristarkh Belopolsky.
1905 Ambartsumian, provisional designation 1972 JZ, is an asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 14 May 1972, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula. The asteroid was named after theoretical astrophysicist Victor Ambartsumian.
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.
