756 Lilliana is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on 26 April 1908 from Taunton, Massachusetts. It rotates around its axis of rotation every 9.36 hours. [5] [ clarification needed ]
Photometric observations of this asteroid at Palmer Divide Observatory in Colorado Springs, Colorado, during 2007 gave a light curve with a period of 9.262±0.001 hours and a brightness variation of 0.83±0.03 in magnitude. [7] A 2012 study based upon observations at the Organ Mesa Observatory in Las Cruces, New Mexico, during 2012 produced a conflicting period of 7.834±0.001 hours and a brightness variation of 0.17±0.02 in magnitude. Further study will be needed to resolve the discrepancies in period and amplitude. [8]
118 Peitho is a main-belt asteroid. It is probably an S-type asteroid, suggesting a siliceous mineralogy. It was discovered by R. Luther on March 15, 1872, and named after one of the two Peithos in Greek mythology. There have been two observed Peithoan occultations of a dim star: one was in 2000 and the other in 2003.
154 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.
209 Dido is a main-belt asteroid with a diameter of 179±1 km. It was discovered by C. H. F. Peters on October 22, 1879, in Clinton, New York and was named after the mythical Carthaginian queen Dido. This asteroid is orbiting the Sun at a distance of 3.15 AU with an eccentricity (ovalness) of 0.058 and a period of 5.59 yr. The orbital plane is tilted at an angle of 7.2° to the plane of the ecliptic.
235 Carolina is a sizeable Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 28 November 1883 in Vienna, and was named after Caroline Island, now part of Kiribati in the Pacific Ocean. This asteroid is orbiting the Sun at a distance of 2.88 AU with a period of 4.89 yr and an eccentricity (ovalness) of 0.06. The orbital plane is tilted at an angle of 9.0° to the plane of the ecliptic.
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.
273 Atropos is a typical Main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 8 March 1888 in Vienna.
275 Sapientia is a very large Main belt asteroid that was discovered by Johann Palisa on 15 April 1888 in Vienna. It is classified as a C-type asteroid and is probably composed of carbonaceous material. It is named for the Roman personification of wisdom, Sapientia.
365 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.
402 Chloë is a large main-belt asteroid. It was discovered by French astronomer Auguste Charlois on 21 March 1895 from Nice. This asteroid is orbiting the Sun at a distance of 2.56 AU with a period of 4.09 years and an eccentricity of 0.11. The orbital plane is inclined at an angle of 11.8° to the plane of the ecliptic.
469 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.
546 Herodias is a carbonaceous asteroid from the central regions of the asteroid belt, approximately 66 kilometers in diameter. It is an identified Eunomian interloper. It was named after the biblical character Herodias.
572 Rebekka is a minor planet orbiting the Sun, which was discovered on September 19, 1905, by a German astronomer Paul Götz in Heidelberg. It was named after a young lady from Heidelberg, and may have been inspired by the asteroid's provisional designation 1905 RB.
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.
630 Euphemia is a mid-sized Eunomian asteroid.
708 Raphaela is a minor planet orbiting the Sun.
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.
947 Monterosa is a minor planet orbiting the Sun.
3037 Alku, provisional designation 1944 BA, is a carbonaceous asteroid from the central region of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 17 January 1944, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland.
1951 Lick, provisional designation 1949 OA, is a rare-type asteroid and Mars-crosser, approximately 5.6 kilometers in diameter. It was discovered on 26 July 1949, by American astronomer Carl Wirtanen at Lick Observatory on the summit of Mount Hamilton, California, and named for American philanthropist James Lick.
2131 Mayall is an inner main-belt asteroid discovered on September 3, 1975, by Arnold Klemola at the Lick Observatory and named in honor of Nicholas U. Mayall (1906–1993), director of the Kitt Peak National Observatory during 1960–1971, who also worked at Lick for many years. It is about 8 km in diameter.
