Simulation of a satellite orbiting a Schwarzschild black hole in a zoom-whirl orbit. The elapsed time for this orbit, assuming a one-solar mass black hole, is 0.018 seconds as viewed by a stationary observer at infinity. The elapsed time on the satellite is 0.016 seconds. The arrow represents the satellite's spin, which is parallel transported along the orbit. (This orbit is
designated (4,1,3) by Levin and Perez-Giz in Phys.Rev.D 77 (2008) 103005.)
