FIGURE 8.51.- The orbit of Pluto with respect to the Sun and to Neptune. The orbital pattern of Pluto librates relative to Neptune, but for clarity the Plutonian orbit is held stationary and the libration of Neptune relative to it is shown. The equilibrium position of Neptune is at a and Neptune librates between extreme positions at b and c with an amplitude of 38°. (From Cohen and Hubbard, 1965.)
