Iris is a large main-belt asteroid and possible remnant planetesimal orbiting the Sun between Mars and Jupiter. It is the fourth-brightest object in the asteroid belt. 7 Iris is classified as an S-type asteroid, meaning that it has a stony composition.
Parthenope is a large, bright main-belt asteroid.
Victoria is a large main-belt asteroid, orbiting the Sun with a period of 3.56 years and an eccentricity of 0.221. It is a stony (S-type) asteroid, about 112–124 km across with an albedo of 0.18 and a rotation period of 8.66 hours. Victoria has been observed to occult a star three times since its discovery. Radar and speckle interferometry observations show that the shape of Victoria is elongated, and it is suspected to be a binary asteroid, with a moon of irregular shape.
Egeria is a large main-belt G-type asteroid. It was discovered by Annibale de Gasparis on November 2, 1850. Egeria was named by Urbain Le Verrier, whose computations led to the discovery of Neptune, after the mythological nymph Egeria of Aricia, Italy, the wife of Numa Pompilius, second king of Rome.
Irene is a large main-belt asteroid, discovered by the English astronomer John Russell Hind on May 19, 1851. It is orbiting the Sun at a distance of 2.585 AU with a period of 4.16 yr and an eccentricity of 0.168. The orbital plane is tilted at an angle of 9.1° to the plane of the ecliptic.
Daphne is a large asteroid from the asteroid belt. It is a dark-surfaced body 174 km in diameter is probably composed of primitive carbonaceous chondrites. The spectra of the asteroid displays evidence of aqueous alteration. It was discovered by H. Goldschmidt on May 22, 1856, and named after Daphne, the nymph in Greek mythology who was turned into a laurel tree. Incorrect orbital calculations initially resulted in 56 Melete being mistaken for a second sighting of Daphne. Daphne was not sighted again until August 31, 1862.
Pales is a large, dark main-belt asteroid. It was discovered by German-French astronomer Hermann Goldschmidt on 19 September 1857 from his balcony in Paris. The asteroid is named after Pales, the goddess of shepherds in Roman mythology. Since it was discovered on the same night as 48 Doris, geologist Élie de Beaumont suggested naming the two "The Twins".
Angelina is an asteroid from the central region of the asteroid belt, approximately 50 kilometers in diameter. It is an unusually bright form of E-type asteroid.
Klio is a fairly large and very dark main-belt asteroid. It was discovered by R. Luther on August 25, 1865, and named after Clio, the Muse of history in Greek mythology. The name Clio had previously been suggested by the discoverer of 12 Victoria, and that is the name B. A. Gould, editor of the prestigious Astronomical Journal, adopted for that asteroid, because of the controversy over the name Victoria. An occultation by Klio over a dim star was observed on April 2, 1997.
Aurora is one of the largest main-belt asteroids. With an albedo of only 0.04, it is darker than soot, and has a primitive composition consisting of carbonaceous material. It was discovered by J. C. Watson on September 6, 1867, in Ann Arbor, and named after Aurora, the Roman goddess of the dawn.
Nemesis is a large 180 km main-belt asteroid, of carbonaceous composition. It rotates rather slowly, taking about 78 hours to complete one rotation. Nemesis is the largest member of the Nemesian asteroid family bearing its name. It was discovered by J. C. Watson on 25 November 1872, and named after Nemesis, the goddess of retribution in Greek mythology.
532 Herculina is a large asteroid, with a diameter of around 200 km.
283 Emma is a large asteroid of the asteroid belt and the namesake of the Emma family. It was discovered by Auguste Charlois on 8 February 1889, in Nice, France. The reason for its name is unknown.
Palma is one of the largest main-belt asteroids. It is a B-type asteroid.
Diotima is one of the larger main-belt asteroids. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.
Gyptis, minor planet designation: 444 Gyptis, is a main-belt asteroid that was discovered by J. Coggia on March 31, 1899, in Marseilles. It is classified as a C-type asteroid and is probably composed of carbonaceous material. The spectra of the asteroid displays evidence of aqueous alteration.
19521 Chaos is a cubewano, a Kuiper-belt object not in resonance with any planet. Chaos was discovered in 1998 by the Deep Ecliptic Survey with Kitt Peak's 4 m telescope. Its albedo is 0.050+0.030
−0.016, making it, with its absolute magnitude (H) of 4.8, equivalent to a single spherical body 600+140
−130 km in diameter.
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.
2244 Tesla, provisional designation 1952 UW1, is a carbonaceous asteroid from the central region of the asteroid belt, approximately 25 kilometers in diameter. It was discovered on 22 October 1952, by Serbian astronomer Milorad Protić at the Belgrade Observatory, then Federal People's Republic of Yugoslavia, now Serbia. It is named after the inventor Nikola Tesla.
2021 RR205 is an extreme trans-Neptunian object and sednoid discovered by astronomers Scott Sheppard, David Tholen, and Chad Trujillo with the Subaru Telescope at Mauna Kea Observatory on 5 September 2021. It resides beyond the outer extent of the Kuiper belt on a distant and highly eccentric orbit detached from Neptune's gravitational influence, with a large perihelion distance of 55.5 astronomical units (AU). Its large orbital semi-major axis (~1,000 AU) suggests it is potentially from the inner Oort cloud. Like 2013 SY99, 2021 RR205 lies in the 50–75 AU perihelion gap that separates the detached objects from the more distant sednoids; dynamical studies indicate that such objects in the inner edge this gap weakly experience "diffusion", or inward orbital migration due to minuscule perturbations by Neptune.
