262 Valda is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 3 November 1886 in Vienna. [3] The name was proposed by Bettina von Rothschild. [4]
Photometric observations of this asteroid from the Organ Mesa Observatory in Las Cruces, New Mexico, during 2010 gave a light curve with a period of 17.386 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 magnitude. [2]
35 Leukothea is a large, dark asteroid from the asteroid belt. It was discovered by German astronomer Karl Theodor Robert Luther on April 19, 1855, and named after Leukothea, a sea goddess in Greek mythology. Its historical symbol was a pharos ; it is in the pipeline for Unicode 17.0 as U+1CED0 .
99 Dike is a quite large and dark main-belt asteroid. Dike was discovered by Alphonse Borrelly on May 28, 1868. It was his first asteroid discovery. This object is named after Dike, the Greek goddess of moral justice. Among the first hundred numbered minor planets, 99 Dike was considered anomalously faint for over a century. However, this was later found to be untrue.
103 Hera is a moderately large main-belt asteroid with an orbital period of 4.44 years. It was discovered by Canadian-American astronomer James Craig Watson on September 7, 1868, and named after Hera, queen and fifth in power of the Olympian gods in Greek mythology. This is a stony S-type asteroid with a silicate surface composition.
149 Medusa is a bright-coloured, stony main-belt asteroid that was discovered by French astronomer J. Perrotin on September 21, 1875, and named after the Gorgon Medusa, a snake-haired monster in Greek mythology. It is orbiting the Sun at a distance of 2.17 AU with a period of 3.21 years and an eccentricity of 0.065. The orbital plane is tilted slightly at an angle of 0.94° to the plane of the ecliptic.
157 Dejanira is a main belt asteroid that was discovered by Alphonse Borrelly on 1 December 1875, and named after the warlike princess Deianira in Greek mythology. The Dejanira family of asteroids is named after it.
188 Menippe is a main belt asteroid. The object has a bright surface and rocky composition. It was discovered by C. H. F. Peters on June 18, 1878, in Clinton, New York, and named after Menippe, one of the daughters of Orion in Greek mythology.
204 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.
217 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.
224 Oceana is an asteroid from the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 30 March 1882, in Vienna. It was named after the Pacific Ocean. Based upon its spectrum, it is classified as an M-type asteroid, but is not metallic.
252 Clementina is a large main belt asteroid that was discovered by French astronomer Henri Joseph Anastase Perrotin on 11 October 1885 in Nice, France. The origin of the name is not known.
256 Walpurga is a large Main belt asteroid. It was discovered by Johann Palisa on 3 April 1886 in Vienna and was named after Saint Walburga.
290 Bruna is a main belt asteroid that was discovered on 20 March 1890 by Johann Palisa, an Austrian astronomer at the Vienna Observatory.
535 Montague is a minor planet orbiting the Sun that was discovered by Raymond Smith Dugan on 7 May 1904 in Heidelberg, Germany. It was named after the town Montague in Massachusetts.
585 Bilkis is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered by German astronomer August Kopff in 1906 February and was given the Koran name for the Queen of Sheba. Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado in 2006–7 were used to build a light curve for this object. The asteroid displayed a rotation period of 8.5742 ± 0.0005 hours and a brightness variation of 0.40 ± 0.02 in magnitude.
605 Juvisia is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered 27 August 1906 in Heidelberg by German astronomer Max Wolf. It was named after the commune Juvisy-sur-Orge, France, where French astronomer Camille Flammarion had his observatory.
620 Drakonia is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered October 26, 1906, in Taunton, Massachusetts, by American astronomer Joel Hastings Metcalf and given the preliminary designation 1906 WE. It may have been named for Drake University.
687 Tinette is a minor planet, specifically an asteroid orbiting primarily in the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 16 August 1909 from Vienna and was given the preliminary designation 1909 HG.
728 Leonisis is an asteroid of the Flora family, discovered by Austrian astronomer Johann Palisa on 16 February 1912 from Vienna.
740 Cantabia is a minor planet orbiting the Sun. It was discovered on 10 February 1913 at Winchester, Massachusetts by American amateur astronomer J. H. Metcalf. Cantabia is a contraction of Cantabrigia, Latin for Cambridge, named in honor of Cambridge, Massachusetts. It is orbiting at a distance of 3.05 AU with a period of 5.33 years and an eccentricity (ovalness) of 0.11. Between 2014 and 2021, 740 Cantabia has been observed to occult three stars.
(523643) 2010 TY53, provisional designation 2010 TY53 is a trans-Neptunian object and possible centaur located in the outermost region of the Solar System. With an absolute magnitude of 5.7, it approximately measures 325 kilometers (200 miles) in diameter. It was discovered on 4 August 2010 by the Pan-STARRS-1 survey at the Haleakala Observatory, Hawaii, in the United States. According to American astronomer Michael Brown, it is "possibly" a dwarf planet.
