899 Jokaste is a minor planet orbiting the Sun. It was one of five minor planets included in the 1993 study, Transition Comets -- UV Search for OH Emissions in Asteroids, which was research involving amateur astronomers who were permitted to make use of the Hubble Space Telescope. Not to be confused with Iocaste, a moon of Jupiter.
261 Prymno is a somewhat large Main belt asteroid. It is classified as a B-type asteroid and probably has a primitive composition not unlike common C-type carbonaceous asteroids.
267 Tirza is a fairly sizeable, very dark Main belt asteroid.
479 Caprera is a minor planet orbiting the Sun.
486 Cremona is a minor planet orbiting the Sun.
500 Selinur is a minor planet, specifically an asteroid orbiting in the asteroid belt. Like 501 Urhixidur and 502 Sigune, it is named after a character in Friedrich Theodor Vischer's then-bestseller satirical novel Auch Einer.
507 Laodica is a minor planet orbiting the Sun.
616 Elly is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
625 Xenia is a minor planet orbiting the Sun. It was discovered by August Kopff in Heidelberg, Germany, on 11 February 1907. The name may have been inspired by the asteroid's provisional designation 1907 XN.
631 Philippina is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on March 21, 1907.
633 Zelima is a minor planet orbiting the Sun in the asteroid belt with a magnitude of 10.7. The name may have been inspired by the asteroid's provisional designation 1907 ZM.
635 Vundtia is a minor planet orbiting the Sun - though this claim has been disputed.
663 Gerlinde is a minor planet orbiting the Sun.
768 Struveana is a minor planet orbiting the Sun. The asteroid was named jointly in honor of Baltic German astronomers Friedrich Georg Wilhelm von Struve, Otto Wilhelm von Struve and Karl Hermann Struve.
839 Valborg is a mid-sized S-type Eunomian asteroid. Its diameter is about 20 km, its albedo of 0.353 is very high for an asteroid. Its rotation period is 10.366 hours.
903 Nealley is a minor planet orbiting the Sun. The semi-major axis of the orbit of 903 Nealley lies just inside the Hecuba gap, located at 3.27 AU.
978 Aidamina, provisional designation 1922 LY, is a dark background asteroid from the outer region of the asteroid belt, approximately 79 kilometers in diameter. It was discovered by astronomer Sergey Belyavsky in 1922, and later named after Aida Minaevna, a friend of the discoverer's family.
Pawlowia, provisional designation 1923 OX, is a background asteroid from the central regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 5 October 1923, by Soviet astronomer Vladimir Albitsky at the Simeiz Observatory on the Crimean peninsula. The asteroid was named after Russian physiologist and Nobelist Ivan Pavlov.
1825 Klare is a background asteroid from the central region of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 31 August 1954, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. The asteroid was named after Heidelberg astronomer Gerhard Klare.
6144 Kondojiro (1994 EQ3) is an asteroid discovered on 14 March 1994 by Kin Endate and Kazuro Watanabe at the Kitami Observatory in eastern Hokkaidō, Japan. It is named after Jiro Kondo, a Japanese Egyptologist and professor of archaeology at Waseda University.
2021 LL37 is a large trans-Neptunian object in the scattered disc, around 600 kilometres (370 miles) in diameter. It was discovered on 12 June 2021, by American astronomers Scott Sheppard and Chad Trujillo using Cerro Tololo Inter-American Observatory's Dark Energy Camera in Chile, and announced on 31 May 2022. It was 73.9 astronomical units from the Sun when it was discovered, making it one of the most distant known Solar System objects from the Sun as of May 2022. It has been identified in precovery images from as far back as 28 April 2014.
