, nicknamed Niku (), is a trans-Neptunian object that has an unusual 110Degree (angle), ° tilted solar orbital plane and retrograde orbit around the Sun. While the object has not received a formal name, it received the moniker "Niku" (逆骨), meaning "rebellious" in the Chinese language, by its discoverers. Details was discovered by the Mount Lemmon Survey on 31 May 2011. Its rediscovery was announced in August 2016 by a team of astronomers using the Pan-STARRS telescope. It was soon linked with a supposed prograde Centaur (minor planet), centaur (; inclination = 38° and semi-major axis = 28 AU) that had been lost due to a short observation arc. is in a 7:9 orbital resonance, resonance with Neptune. Currently it is the only object with a nearly polar orbit that is in resonance with a planet. Notably, it is part of a group of objects that orbit the Sun in a highly inclined orbit; the reasons for this unusual orbit are unknown as of August 2016. The orbital characteristics of ...

Mount Lemmon Survey
Mount Lemmon Survey (MLS) is a part of the Catalina Sky Survey with List of observatory codes, observatory code List of observatory codes#G96, G96. MLS uses a cassegrain reflector telescope (with 10560x10560-pixel camera at the f/1.6 prime focus, for a five square degree field of view) operated by the Steward Observatory at Mount Lemmon Observatory, which is located at in the Santa Catalina Mountains northeast of Tucson, Arizona. It is currently one of the most prolific surveys worldwide, especially for discovering near-Earth objects. MLS ranks among the top discoverers on the Minor Planet Center's discovery chart with a total of more than 50,000 numbered minor planets. History Andrea Boattini and the survey accidentally rediscovered 206P/Barnard-Boattini, a lost comet, on 7 October 2008. The comet has made 20 revolutions since 1892 and passed within 0.3–0.4 Astronomical unit, AU of Jupiter in 1922, 1934 and 2005. This comet was also the first comet to be discovered b ...
