Papagena (minor planet designation: 471 Papagena) is an asteroid that was discovered by German astronomer Max Wolf on 7 June 1901. [1] Its provisional name was 1901 GN.
Papagena comes to a favorable near-opposition apparent magnitude of better than magnitude 9.8 every five years. On 30 September 2010, it was magnitude 9.68 and it will get brighter every five years until 12 December 2035, when this late-to-be-discovered asteroid will be at magnitude 9.28. It is named for a character in Mozart's opera, The Magic Flute .[ citation needed ]
Melete is a large and dark main belt asteroid. It is a rather unusual P-type asteroid, probably composed of organic rich silicates, carbon and anhydrous silicates, with possible internal water ice. The asteroid orbits the Sun with a period of 4.18 years.

The asteroid is orbiting the Sun at a distance of 2.67 AU with a period of 4.35 yr and an orbital eccentricity of 0.206. The orbital plane is inclined at an angle of 2.10° to the plane of the ecliptic.
Bamberga is one of the largest asteroids in the asteroid belt. It was discovered by Johann Palisa on 25 February 1892 in Vienna. It is one of the top-20 largest asteroids in the asteroid belt. Apart from the near-Earth asteroid Eros, it was the last asteroid which is ever easily visible with binoculars to be discovered.
Gudrun is a main-belt asteroid.
Eleonora is a large, stony main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 17, 1893, in Nice.
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.
Aurelia is a main-belt asteroid that was discovered by German astronomer Max Wolf on September 7, 1896, in Heidelberg. It is classified as an F-type asteroid.
Patientia is approximately the 15th-largest asteroid in the asteroid belt with a diameter of 225 km. It was discovered by French astronomer Auguste Charlois on 4 December 1899, and assigned a provisional designation 1899 EY.
Argentina is an asteroid that was discovered by Luigi Carnera on 20 February 1901. Its provisional name was 1901 GE. 469 Argentina has an estimated rotation period of 12.3 hours.

Tekmessa is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on February 16, 1906. The name may have been inspired by the asteroid's provisional designation 1906 TK.
665 Sabine is a minor planet orbiting the Sun that was discovered by German astronomer Wilhelm Lorenz on July 22, 1908.

1171 Rusthawelia, provisional designation 1930 TA, is a large and dark background asteroid, approximately 72 kilometers in diameter, located in the outer regions of the asteroid belt. It was discovered on 3 October 1930, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, and was an unnoticed rediscovery of a lost minor planet then known as "Adelaide". As the asteroid was already named for Georgian poet Shota Rustaveli when the rediscovery was realized, its former designation was given to another asteroid instead, which is now known as 525 Adelaide. Rusthawelia is a primitive P-type asteroid and has a rotation period of 11 hours.
