Gudrun (minor planet designation: 328 Gudrun) is a main-belt asteroid.
It was discovered by Max Wolf on March 18, 1892, in Heidelberg.
Analysis of the light curve generated from photometric data collected in March 2012 provide a rotation period estimate of 10.992±0.002 h with a brightness variation of 0.32±0.02 in B magnitude. [4]
Laetitia is a large main-belt asteroid that was discovered by French astronomer Jean Chacornac on 9 February 1856 and named after Laetitia, a minor Roman goddess of gaiety. The spectrum matches an S-type, indicating a stony (silicate) composition. It is orbiting the Sun with a period of 4.61 years and is spinning on its axis once every 5.1 hours.
Frigga is a large, M-type, possibly metallic main-belt asteroid. It was discovered by the German-American astronomer C. H. F. Peters on November 12, 1862. The object is named after Frigg, the Norse goddess. The asteroid is orbiting the Sun with a period of 4.36 years and completes a rotation on its axis every nine hours.
Diana is a large and dark main-belt asteroid. It was discovered by German astronomer Robert Luther on March 15, 1863, and named after Diana, Roman goddess of the hunt. The asteroid is orbiting the Sun at a distance of 2.620 AU with a period of 4.24 years and an eccentricity (ovalness) of 0.207. The orbital plane is tilted at an angle of 8.688° relative to the plane of the ecliptic. Its composition is carbonaceous and primitive.
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.
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.
Eunike is a dark and very large main-belt asteroid, with an approximate diameter of 157 kilometres. It has a primitive carbonaceous composition.
Nausikaa is a large main-belt S-type asteroid. It was discovered by Johann Palisa on February 17, 1879, at Pula, then in Austria, now in Croatia. The name derives from Nausicaä, a princess in Homer's Odyssey.
Prokne is a main-belt asteroid that was discovered by German-American astronomer C. H. F. Peters on March 21, 1879, in Clinton, New York, and named after Procne, the sister of Philomela in Greek mythology. Stellar occultations by Prokne have been observed twice, in 1984 from Italy and again in 1999 from Iowa.
Kallisto is a fairly typical, although sizeable Main belt asteroid. It is classified as an S-type asteroid. Like other asteroids of its type, it is light in colour. It was discovered by Johann Palisa on 8 October 1879, in Pola, and was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto.
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.
Aline is a fairly large main belt asteroid that was discovered by Johann Palisa on 17 May 1887 in Vienna and is thought to have been named after the daughter of astronomer Edmund Weiss. It is a dark C-type asteroid and is probably composed of primitive carbonaceous material. 266 Aline is orbiting close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 AU.
Hermentaria is a very large main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 25 November 1892, in Nice. It is probably named for the town of Herment in the region of Auvergne, France. The asteroid is orbiting the Sun with a period of 4.68 years and an eccentricity (ovalness) of 0.10. The orbital plane is inclined by 8.7° to the plane of the ecliptic.
Corduba is a very large main-belt asteroid that was discovered by the French astronomer Auguste Charlois on 21 March 1893 from Nice. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
Semiramis is a minor planet orbiting the Sun within the main asteroid belt. Photometric observations at the Mark Evans Observatory during 2014 gave a rotation period of 5.0689 ± 0.0001 hours. This value is in close agreement with previous studies. The spectrum shows it to be a stony S(IV)-type asteroid.
654 Zelinda is a minor planet orbiting the Sun that was discovered on 4 January 1908 by German astronomer August Kopff. On favorable oppositions, it can be as bright as magnitude 10.0, as on January 30, 2016.
690 Wratislavia is a minor planet orbiting the Sun. Wratislavia was discovered on October 16, 1909. IRAS data shows it is about 135 km in diameter.
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.
758 Mancunia is a minor planet orbiting the Sun. It was discovered in 1912 from Johannesburg by H. E. Wood, a Mancunian. This object is orbiting at a distance of 3.19 AU with a period of 5.70 years and an eccentricity (ovalness) of 0.15. The orbital plane is inclined at an angle of 5.61° to the plane of the ecliptic.
804 Hispania is a minor planet orbiting the Sun. It was discovered from Barcelona (Spain) on 20 March 1915 by Josep Comas Solá (1868–1937), the first asteroid to be discovered by a Spaniard.
