Premise: New Horizons . After a brief encounter with asteroid 132524 APL , New Horizons proceeded to Jupiter , making its closest approach on February 28 , 2007 , at a distance of 2.3 e6km . The Jupiter flyby provided a gravity assist that increased New Horizons speed ; the flyby also enabled a general test of New Horizons scientific capabilities , returning data about the planet 's atmosphere , moons , and magnetosphere .
