It was first observed by the Mount Lemmon Survey on 13 March 2005.[1] The unusual minor planet follows an orbit similar to those of the fragments of comet Shoemaker–Levy 9.[14] This minor planet has neither been numbered nor named.[1] Description{{mp|2017 UV|43}} is classified as an unusual object and centaur.[3][4] It was first observed by the Mount Lemmon Survey on 13 March 2005. Previously, before the identification with {{mp|2005 EE|207}} was made, the first observation was made on 27 October 2017 by the Pan-STARRS program at Haleakala Observatory, Hawaii, United States.[1]It orbits the Sun at a distance of 5.0–8.5 AU once every 17 years and 6 months (6,387 days; semi-major axis of 6.74 AU). Its orbit has an eccentricity of 0.26 and an inclination of 5° with respect to the ecliptic. The body's observation arc begins with its first observation by the Mount Lemmon Survey in March 2005.[1] Comet Shoemaker–Levy 9As of December 2017, {{mp|2017 UV|43}} has an orbit similar to the average one of the fragments of comet Shoemaker–Levy 9 (semi-major axis: {{val|6.81|0.04|u=AU}} , eccentricity: {{val|0.210|0.004}}, inclination: {{val|5.87|0.08|ul=°}}, longitude of the ascending node: {{val|220.8|0.2|ul=°}} and argument of perihelion: {{val|354.98|0.05|ul=°}}).[14] References1. ^1 2 3 4 5 6 7 {{cite web |title = 2017 UV43 |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=2017+UV43 |accessdate = 19 November 2018}} [1][2][3][4][5]2. ^1 2 {{cite web |title = List Of Other Unusual Objects |work = Minor Planet Center |date = 14 November 2018 |url = https://www.minorplanetcenter.net/iau/lists/t_others.html |accessdate = 19 November 2018}} 3. ^1 2 3 4 {{cite web |title = List of Known Trans-Neptunian Objects |work = Johnston's Archive |date = 7 October 2018 |author = Johnston, Wm.
