    (315898) 2008 QD4, also written as (315898) 2008 QD4, is a centaur with a perihelion greater than Jupiter and a semi-major axis less than Saturn.

    Perihelion

    (315898) 2008 QD4 is listed as a centaur by the Minor Planet Center (MPC),[3] JPL,[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 41° orbital inclination, it is above the ecliptic plane when crossing Jupiters orbit, and below the ecliptic when crossing Saturns orbit.
