737 Arequipa is a minor planet orbiting the Sun. It was discovered by American astronomer Joel Hastings Metcalf on 7 December 1912 from Winchester, Massachusetts. This stony S-type asteroid was named after the Peruvian city of Arequipa, where Harvard's Boyden Observatory was located prior to 1927. It is orbiting at a distance of 2.59 AU from the Sun, with an orbital eccentricity (ovalness) of 0.245 and a period of 4.17 yr. The orbital plane is inclined at an angle of 12.4° to the ecliptic. [1]
The rotation period of this asteroid has proven to be a challenge to determine, most likely because it has a complex shape and a rotation axis with a low inclination. However, during the 2015 apparition, photometric measurements of the asteroid were taken from close to the equatorial perspective. The resulting light curve displayed a rotation period of 7.0259±0.0003 h. [2]
Pandora is a fairly large and very bright asteroid in the asteroid belt. Pandora was discovered by American astronomer and Catholic priest George Mary Searle on September 10, 1858, from the Dudley Observatory near Albany, NY. It was his first and only asteroid discovery.
Panopaea is a large main belt asteroid. Its orbit is close to those of the Eunomia asteroid family; however, Panopaea is a dark, primitive carbonaceous C-type asteroid in contrast to the S-type asteroids of the Eunomian asteroids. The spectra of the asteroid displays evidence of aqueous alteration. Photometric studies give a rotation period of 15.797 hours and an amplitude of 0.11±0.01 in magnitude. Previous studies that suggested the rotation period may be twice this amount were rejected based upon further observation.
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.
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.
Vera is a large Main belt asteroid. It was discovered by N. R. Pogson on February 6, 1885, in Madras, and was named at the suggestion of his wife. The asteroid is orbiting the Sun at a distance of 3.11 AU with a period of 5.47 years and an eccentricity (ovalness) of 0.19. The orbital plane is tilted at an angle of 5.16° to the plane of the ecliptic. In 1890, Daniel Kirkwood noted that this asteroid shares similar orbital elements with 86 Semele and 106 Dione.
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.
Iclea is a large main belt asteroid with the minor planet designation, 286 Iclea. It was discovered by Austrian astronomer Johann Palisa on 3 August 1889 in Vienna, and named for the heroine of Camille Flammarion's astronomical romance Uranie. This object is orbiting the Sun at a distance of 3.19 AU with a period of 5.711 years and an orbital eccentricity (ovalness) of 0.029. The orbital plane is tilted at an angle of 17.9° to the plane of the ecliptic.
Etheridgea is a large main belt asteroid. It was discovered by Auguste Charlois on 1 April 1892 in Nice. The meaning of the name is unknown. This asteroid is orbiting the Sun at a distance of 3.02 AU with a period of 5.26 years and an eccentricity (ovalness) of 0.10. The orbital plane is tilted at an angle of 6.05° to the plane of the ecliptic.
May is a large Main belt asteroid. It was discovered by Auguste Charlois on 28 November 1892 in Nice, and was named for the German author Karl May. This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.12 years and an eccentricity (ovalness) of 0.067. The orbital plane is inclined at an angle of 9.7° to the plane of the ecliptic. During its orbit, this asteroid has made close approaches to the dwarf planet Ceres. For example, in September 1984 the two were separated by 6.3 Gm (0.042 AU).
Edburga is a typical Main belt asteroid. Max Wolf discovered it on 7 January 1896 at Heidelberg Observatory. The origin of the name is unknown. This asteroid is orbiting the Sun at a distance of 2.58 AU with a period of 4.15 yr and an eccentricity of 0.34. Its orbital plane is inclined at an angle of 18.7° to the plane of the ecliptic.
Petrina is a minor planet orbiting the Sun.
Stereoskopia is a large, outer main-belt asteroid orbiting the Sun. It was discovered on 28 May 1905 from Heidelberg by German astronomer Paul Götz. The discovery was made from photographic plates with the use of a stereo-comparator that had been provided by Carl Pulfrich, a German physicist at the Carl Zeiss Company. The asteroid name is a reference to this device.
673 Edda is a minor planet orbiting the Sun. It was discovered 20 September 1908 by the American astronomer Joel Hastings Metcalf, and was named for the Norse Edda literary works. The name may also have been inspired by the asteroid's provisional designation 1908 EA. This asteroid is orbiting at a distance of 2.81 AU with a period of 4.72 yr and an eccentricity of 0.012. The orbit is close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 AU.
736 Harvard is a stony background asteroid from the inner regions of the asteroid belt, approximately 17 kilometers in diameter. It was discovered on 16 November 1912, by American astronomer Joel Hastings Metcalf at the Winchester Observatory. The bright S-type asteroid has a rotation period of 6.7 hours. It was named after Harvard University in Cambridge, Massachusetts.
815 Coppelia is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 2 February 1916 from Heidelberg named after Coppélia, a comic ballet.
1997 Leverrier is a stony Flora asteroid from the inner regions of the asteroid belt. It was discovered on 14 September 1963, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States, and named after French mathematician Urbain Le Verrier. The asteroid has a rotation period of 6.8 hours and measures approximately 7 kilometers in diameter
1675 Simonida, provisional designation 1938 FB, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 11 kilometers in diameter. Discovered by Milorad Protić in 1938, it was later named after the medieval Byzantine princess Simonida.
3174 Alcock is a carbonaceous Themistian asteroid from the outer region of the asteroid belt. It was discovered by American astronomer Edward Bowell at Lowell's U.S. Anderson Mesa Station in Flagstaff, Arizona, on 26 October 1984. The likely C-type asteroid has a rotation period of 7.1 hours and measures approximately 19 kilometers in diameter. It was named after British amateur astronomer George Alcock (1912–2000).
151997 Bauhinia, provisional designation 2004 JL1, is a sub-kilometer background asteroid from the inner regions of the asteroid belt, approximately 900 meters in diameter. It was discovered on 11 May 2004, by Canadian astronomer William Yeung at the Desert Eagle Observatory, Arizona, United States. It was named after the flowering plant Bauhinia blakeana also known as the "Hong Kong Orchid Tree".
(445473) 2010 VZ98, provisional designation 2010 VZ98, is a trans-Neptunian object of the scattered disc, orbiting the Sun in the outermost region of the Solar System. It has a diameter of approximately 400 kilometers.
