658 Asteria is a minor planet orbiting the Sun.
199 Byblis is a medium-sized main belt asteroid.
Phaëtusa is a small Main belt asteroid. It was discovered by Auguste Charlois on 19 August 1890 in Nice.
Margarita is a typical Main belt asteroid. It was discovered by Auguste Charlois on 16 May 1891 in Nice.
343 Ostara is a background asteroid from the inner region of the asteroid belt. It was discovered by German astronomer Max Wolf at the Heidelberg Observatory on 15 November 1892.
Seppina is a minor planet orbiting the Sun.
Mabella is a minor planet orbiting the Sun.
Sara is a minor planet orbiting the Sun.
Nassovia is a minor planet orbiting the Sun. It is a member of the Koronis family of asteroids.
609 Fulvia is a minor planet orbiting the Sun.
615 Roswitha is a minor planet orbiting the Sun.
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.

726 Joëlla is a minor planet orbiting the Sun. It was discovered on November 22, 1911, by Joel Hastings Metcalf, in Winchester, Massachusetts, in the United States.
818 Kapteynia is a minor planet orbiting the Sun. This asteroid is named for the Dutch astronomer Jacobus Kapteyn.
819 Barnardiana is a minor planet orbiting the Sun, discovered on March 3, 1916, by the German astronomer Max Wolf in Heidelberg.
872 Holda is a minor planet orbiting the Sun.
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.
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.
