    Libussa (minor planet designation: 264 Libussa) is a Main belt asteroid that was discovered by C. H. F. Peters on December 22, 1886, in Clinton, New York and was named after Libussa, the legendary founder of Prague. [3] It is classified as an S-type asteroid.

    Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico, in 2008 gave an asymmetrical, bimodal light curve with a period of 9.2276 ± 0.0002 hours and a brightness variation of 0.33 ± 0.03 in magnitude. [2] Observation from the W. M. Keck Observatory show an angular size of 57 mas, which is close to the resolution limit of the instrument. The estimated maximum size of the asteroid is about 66 ± 7 km. It has an asymmetrical shape with a size ratio of more than 1.22 between the major and minor axes. [4]

    Between 2005 and 2021, 264 Libussa has been observed to occult five stars.

    Urania is a large main-belt asteroid that was discovered by English astronomer John Russell Hind on July 22, 1854. It was his last asteroid discovery. This object is named after Urania, the Greek Muse of astronomy. Initial orbital elements for 30 Urania were published by Wilhelm Günther, an assistant at Breslau Observatory. It is orbiting the Sun with a period of 3.64 years and is spinning on its axis once every 13.7 hours.

    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.

    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.

    Hermione is a very large binary asteroid discovered in 1872. It orbits in the Cybele group in the far outer asteroid belt. As an asteroid of the dark C spectral type, it is probably composed of carbonaceous materials. In 2002, a small moon was found to be orbiting Hermione.

    137 Meliboea is a large, dark main-belt asteroid that was discovered by Austrian astronomer J. Palisa at the Austrian Naval Observatory on 21 April 1874, the second of his many asteroid discoveries. It was later named after Meliboea, the daughter of Oceanus and Tethys in Greek mythology. The largest body in the Meliboea family of asteroids that share similar orbital elements, only 791 Ani approaches its size. It is classified as a C-type asteroid and may be composed of carbonaceous materials. The spectra of the asteroid displays evidence of aqueous alteration.

    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.
