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 ]
Circe, minor planet designation 34 Circe, is a large, very dark main-belt asteroid. It was discovered by French astronomer J. Chacornac on April 6, 1855, and named after Circe, the bewitching queen of Aeaea island in Greek mythology.
Galatea is a large C-type main-belt asteroid. Its carbonaceous surface is very dark in color with an albedo of just 0.034. Galatea was found by the prolific comet discoverer Ernst Tempel on August 29, 1862, in Marseilles, France. It was his third asteroid discovery. It is named after one of the two Galateas in Greek mythology. A stellar occultation by Galatea was observed on September 8, 1987. The name Galatea has also been given to one of Neptune's satellites.
Velleda is a main-belt asteroid. It is probably a rather typical, albeit sizable, S-type asteroid. Named for Veleda, a priestess and prophet of the Germanic tribe of the Bructeri. It was discovered by Paul Henry on November 5, 1872, in Paris, France. It was his first credited discovery. He and his brother Prosper Henry discovered a total of 14 asteroids.
Phthia is a bright-coloured, rocky main belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on September 9, 1878 in Clinton, New York and named after Phthia, a region of Ancient Greece.
Medea is a very large main-belt asteroid that was discovered by Johann Palisa on February 6, 1880, in Pola, and was named after Medea, a figure in Greek mythology.
Eudora is a large Main belt asteroid. It was discovered by French (Corsican) astronomer J. Coggia on August 30, 1880, in Marseilles, France. It was his fourth asteroid discovery and is named after Eudora, a Hyad in Greek mythology.
Vanadis is a fairly large main-belt asteroid with a diameter of around 100 km. It was discovered by A. Borrelly on August 27, 1884, in Marseilles and was named after Freyja (Vanadis), the Norse fertility goddess. 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.
Emita is a minor planet orbiting the Sun that was discovered by the Italian astronomer Luigi Carnera on February 12, 1902. The meaning of the asteroid's proper name remains unknown.
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.
619 Triberga is a main belt asteroid discovered on 22 October 1906 by August Kopff at Heidelberg-Königstuhl State Observatory. Since it has an orbit that repeats itself almost exactly every four years with respect to the position of the Sun and Earth, it has been suggested as a way to calculate the mass of the Moon. Triberga was named for the German town of Triberg.
665 Sabine is a minor planet orbiting the Sun that was discovered by German astronomer Wilhelm Lorenz on July 22, 1908.
747 Winchester is an asteroid, a minor planet orbiting the Sun. It was discovered in 1913, and is named after the town in which it was discovered, Winchester, Massachusetts, in the USA.
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.
