Perihelion 2008 QD 4 is listed as a centaur by the Minor Planet Center, Jet Propulsion Laboratory, and the Deep Ecliptic Survey (DES). Of numbered objects listed as a centaur by all 3 major institutions, 2008 QD 4 has the smallest perihelion distance. It came to perihelion in August 2010. thumb|left|450px|Of objects listed as a centaur by all 3 major institutions, 2008 QD 4 has the smallest perihelion distance. Due to a 41° orbital inclination, it is above the ecliptic plane when crossing Jupiter's orbit, and below the ecliptic when crossing Saturn's orbit. left See also List of centaurs (small Solar System bodies) 315898 References last observation: 2008-10-08 JPL Small-Body Database Browser: (2008 QD4) https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2008QD4 8 April 2016 List Of Centaurs and Scattered-Disk Objects Minor Planet Center http://www.minorplanetcenter.org/iau/lists/Centaurs.html 2008-10-17 Marc W.
