    Urda is a main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on August 28, 1876, in Clinton, New York, and named after Urd, one of the Norns in Norse mythology. In 1905, Austrian astronomer Johann Palisa showed that the asteroid varied in brightness.

    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.
