    Perihelion

    2008 QD4 is listed as a centaur by the Minor Planet Center, [3] Jet Propulsion Laboratory, [1] and the Deep Ecliptic Survey (DES). [2] Of numbered objects listed as a centaur by all 3 major institutions, (315898) 2008 QD4 has the smallest perihelion distance. [3]

    It came to perihelion in August 2010. [1]

    Of objects listed as a centaur by all 3 major institutions, (315898) 2008 QD4 has the smallest perihelion distance. Due to a 41deg orbital inclination, it is above the ecliptic plane when crossing Jupiter's orbit, and below the ecliptic when crossing Saturn's orbit. 2008QD4-orbit.png
