Zelia (minor planet designation: 169 Zelia) is a main belt asteroid that was discovered by the brothers Paul Henry and Prosper Henry on September 28, 1876. Credit for this discovery was given to Prosper. [3] Initial orbital elements for this asteroid were published in 1877 by American astronomer H. A. Howe. [4]
Based upon its spectrum, this body is classified as a rare O-type asteroid in the taxonomic system of Bus & Binzel. [2] Photometric observations of this asteroid during 2009 gave a light curve with a period of 14.537 ± 0.001 hours and a brightness variation of 0.14 ± 0.03 in magnitude. [5]
It was named for Zelia Martin, a niece of the astronomer Camille Flammarion. [6]
Virginia is a large, very dark main belt asteroid. It was discovered by American astronomer James Ferguson on October 4, 1857, from the United States Naval Observatory in Washington, D.C. German astronomer Robert Luther discovered it independently on October 19 from Düsseldorf, and his discovery was announced first.
Lachesis is a large main-belt asteroid. It was discovered by French astronomer Alphonse Borrelly on April 10, 1872, and independently by German-American astronomer Christian Heinrich Friedrich Peters on April 11, 1872, then named after Lachesis, one of the Moirai, or Fates, in Greek mythology. A Lachesean occultation of a star occurred in 1999 and was confirmed visually by five observers and once photoelectrically, with the chords yielding an estimated elliptical cross-section of 184 × 144 km.
164 Eva is a main-belt asteroid that was discovered by the French brothers Paul Henry and Prosper Henry on July 12, 1876, in Paris. The reason the name Eva was chosen remains unknown. The orbital elements for 164 Eva were published in 1877 by American astronomer Winslow Upton. It is categorized as a C-type asteroid and is probably composed of primitive carbonaceous chondritic materials.
Phaedra is a sizable, rocky main belt asteroid that was discovered by Canadian-American astronomer James Craig Watson on September 2, 1877, and named after Phaedra, the tragic lovelorn queen in Greek mythology.
Iduna is a large main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on October 14, 1877, in Clinton, New York. It is named after Sällskapet Idun, a club in Stockholm that hosted an astronomical conference; Idun is also a Norse goddess. A G-type asteroid, it has a composition similar to that of the largest main-belt asteroid, 1 Ceres.
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.
Celuta is a 50 km Main belt asteroid. It was discovered by the French astronomers Paul Henry and Prosper Henry on April 6, 1878. This was the last discovery credited to the Prosper brothers. It is classified as an S-type asteroid.
Oppavia is a sizeable Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 31 March 1886 in Vienna and was named after Opava, a town in the Czech Republic, then part of Austria-Hungary, where Palisa was born. It is orbiting the Sun at a distance of 2.75 AU with an orbital eccentricity (ovalness) of 0.077 and a period of 4.55 yr. The orbital plane is inclined by an angle of 9.47° to the plane of the ecliptic.
Valda is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 3 November 1886 in Vienna. The name was proposed by Bettina von Rothschild.
Penthesilea is a mid-sized main belt asteroid that was discovered by Viktor Knorre on 13 October 1887 in Berlin. It was his last asteroid discovery. The asteroid was named after Penthesilea, the mythical Greek queen of the Amazons.
Bruna is a main belt asteroid that was discovered on 20 March 1890 by Johann Palisa, an Austrian astronomer at the Vienna Observatory.
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.
611 Valeria is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on September 24, 1906, from Taunton, Massachusetts. The name may have been inspired by the asteroid's provisional designation 1906 VL.
650 Amalasuntha is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on October 4, 1907, at Heidelberg. It was named after Amalasuntha, the queen of the Ostrogoths from 526 to 534 AD. The name may have been inspired by the asteroid's provisional designation 1907 AM.
718 Erida is a minor planet orbiting the Sun. It was discovered at Vienna on September 29, 1911, by Austrian astronomer Johann Palisa, and was named for Erida Leuschner, daughter of astronomer Armin Otto Leuschner. It is orbiting at a distance of 3.06 AU with a period of 5.34 yr and an eccentricity of 0.20. The orbital plane of this asteroid is inclined by an angle of 6.9° to the plane of the ecliptic.
774 Armor is a minor planet orbiting in the main belt. It was discovered on December 13, 1913, in Paris by French astronomer Charles le Morvan and was named after the Celtic region of Armorica. The asteroid is orbiting at a distance of 3.05 AU with a period of 5.32 yr and an eccentricity of 0.169. The orbital plane is inclined by an angle of 5.56° to the plane of the ecliptic.
860 Ursina is a minor planet orbiting the Sun that was discovered in 1917 by German astronomer Max Wolf. The origin of the name is unknown.
967 Helionape is an asteroid belonging to the Flora family of Main Belt asteroids. It was discovered by German astronomer Walter Baade at Hamburg Observatory on November 9, 1921, and was named after the Austrian theatrical actor Adolf von Sonnenthal. This object is orbiting the Sun at a distance of 2.23 AU with a period of 3.32 years and an eccentricity of 0.168. The orbital plane is inclined at an angle of 5.4° to the ecliptic.
