2436 Hatshepsut, provisional designation 6066 P-L, is a Hygiean asteroid from the outer asteroid belt, approximately 19 kilometers in diameter. It was discovered by Cornelis van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory on 24 September 1960. It was named for pharaoh Hatshepsut.
10 Hygiea is a major asteroid located in the main asteroid belt. With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids in classifications that use G type for 1 Ceres. It is very close to spherical, apparently because it had re-accreted after the disruptive impact that produced the large Hygiean family of asteroids.
53 Kalypso is a large and very dark main belt asteroid that was discovered by German astronomer Robert Luther on April 4, 1858, at Düsseldorf. It is named after Calypso, a sea nymph in Greek mythology, a name it shares with Calypso, a moon of Saturn.
104 Klymene is a large, dark Themistian asteroid that was discovered by J. C. Watson on September 13, 1868, and named after one of the many Clymenes in Greek mythology. It is orbiting the Sun with a period of 5.60 years and an eccentricity of 0.16. The orbital plane is inclined by 2.8° to the plane of the ecliptic. It is classified as a C-type asteroid, indicating it probably has a carbonaceous composition. The spectra indicates the presence of aqueous-altered minerals on the surface based upon a sharp feature at a wavelength of 3 μm, and, as of 2015, is the only member of the Themis family found to show this absorption.
106 Dione is a large main-belt asteroid. It probably has a composition similar to 1 Ceres. It was discovered by J. C. Watson on October 10, 1868, and named after Dione, a Titaness in Greek mythology who was sometimes said to have been the mother of Aphrodite, the Greek goddess of love and beauty. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter. The orbital period for this object is 5.66 years and it has an eccentricity of 0.17.
108 Hecuba is a fairly large and bright main-belt asteroid. It was discovered by Karl Theodor Robert Luther on 2 April 1869, and named after Hecuba, wife of King Priam in the legends of the Trojan War in Greek Mythology. This object is orbiting the Sun with a period of 5.83 years and an eccentricity of 0.06. It became the first asteroid discovered to orbit near a 2:1 mean-motion resonance with the planet Jupiter, and is the namesake of the Hecuba group of asteroids.
122 Gerda is a fairly large outer main-belt asteroid that was discovered by German-American astronomer C. H. F. Peters on July 31, 1872, and named after Gerðr, the wife of the god Freyr in Norse mythology. Based upon its spectrum, this is classified as an S-type asteroid. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter.
133 Cyrene is a fairly large and very bright main-belt asteroid that was discovered by J. C. Watson on 16 August 1873 in Ann Arbor, Michigan, and named after Cyrene, a nymph, daughter of king Hypseus and beloved of Apollo in Greek mythology. It is classified as an S-type asteroid based upon its spectrum. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter.
147 Protogenia is a large main belt asteroid that was discovered by Hungarian astronomer Lipót Schulhof on July 10, 1875, from the Vienna Observatory; it was his only asteroid discovery. Its name is Greek for "first born" and was chosen by Karl L. Littrow in allusion to the fact that this was the first asteroid discovered by an astronomer who was already known for work in other fields of astronomy.
150 Nuwa is a large main-belt asteroid with an orbital period of 5.15 years. It was discovered by Canadian-American astronomer James Craig Watson on October 18, 1875, and named after Nüwa, the Chinese creator goddess. This object is a candidate member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter. Based upon the spectrum it is classified as a C-type asteroid, which indicates that it is probably composed of primitive carbonaceous chondritic material and the surface is exceedingly dark.
159 Aemilia is a large main-belt asteroid. Aemilia was discovered by the French brothers Paul Henry and Prosper Henry on January 26, 1876. The credit for this discovery was given to Paul. It is probably named after the Via Aemilia, a Roman road in Italy that runs from Piacenza to Rimini.
175 Andromache is a main-belt asteroid that was discovered by Canadian-American astronomer J. C. Watson on October 1, 1877, and named after Andromache, wife of Hector during the Trojan War. Watson's telegram to Europe announcing the discovery became lost, and so notification did not arrive until several weeks later. As a result, another minor planet, later designated 176 Iduna, was initially assigned the number 175.
255 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.
258 Tyche is a relatively large main belt asteroid discovered by Robert Luther at Düsseldorf-Bilk Observatory on 4 May 1886. The stony S-type asteroid measures about 65 kilometers in diameter and has a perihelion of 2.1 AU.
538 Friederike is a minor planet orbiting in the asteroid belt. It is a member of the Hygiea family of asteroids.
867 Kovacia is an elongated, dark asteroid and member of the Hygiea family from the outer regions of the asteroid belt. It was discovered on 25 February 1917, by astronomer Johann Palisa at the Vienna Observatory in Austria. The carbonaceous C/B-type asteroid has a rotation period of 8.7 hours and measures approximately 24 kilometers in diameter. It was named after Austrian physician Friedrich Kovacs (1861–1931).
63305 Bobkepple is a carbonaceous Hygiean asteroid from the outer regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 17 March 2001, by astronomer David Healy at the Junk Bond Observatory in Arizona, United States. The asteroid was named after Bob Kepple, co-author of The Night Sky Observer's Guide.
22740 Rayleigh (provisional designation 1998 SX146) is a Zhongguo asteroid from the outermost region of the asteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 20 September 1998, by Belgian astronomer Eric Elst at the La Silla Observatory in Chile. It is one of few asteroids located in the 2 : 1 resonance with Jupiter. The asteroid was named for English physicist and Nobel laureate Lord Rayleigh.
5201 Ferraz-Mello is an asteroid from the asteroid belt, discovered on 1 December 1983 by Ted Bowell at the Anderson Mesa Station of the Lowell Observatory. It is one of very few Hecuba-gap asteroids located in the 2:1 mean motion resonance with Jupiter.
(16882) 1998 BO13 (provisional designation 1998 BO13) is a dark Zhongguo asteroid from the background population in the outermost region of the asteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 24 January 1998, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.
