English: Photon orbit below the ergosphere and above the horizon of an extremal Kerr black hole. Spin parameter: a=1, direction of motion: prograde. Initial conditions: radius r=1.448GM/c², polar angle θ=90°, local equatorial inclination angle i=66.1391°, constants of motion: energy E=0.475744hf, axial angular momentum Lz=0.856004GMhf/c³, Carter constant Q=1.75361GMHf/c³. Left: x,z-projection, right: x,y-projection. For a close particle orbit see
