  Recent imaging campaigns indicate the likely existence of massive planets (~
1-10 MJ) on ~1000 year orbits about a few percent of stars. Such objects are
not easily explained in most current planet formation models. In this Letter we
use ensembles of 100 N-body simulations to evaluate the potential for planet
scattering during relaxation of dynamically active systems to explain the
population of giant planets with projected separations up to a few 100 AU. We
find that such a mechanism could indeed be at play, and that statistical
samples of long period planets could place interesting constraints on early
stage planet formation scenarios. Results from direct imaging and microlensing
surveys are complementary probes of this dynamical relaxation process.
