Figure 6: Unperturbed hyperbola of NEAR; its osculating plane is tilted by 108 deg to the $\{x\mathrm{,}y\}$ plane assumed coincident with the Earth equator. The starting point is in the right upper corner ($x_0>0,y_0>0,z_0>0$). The Earth has to be imagined located at the origin of the coordinate system with its spin $S$ directed along the positive $z$ axis.
