2 km s-1. The resulting (idealized) trajectory is a parabola with respect to the center of the Earth. As viewed in a heliocentric inertial coordinate system, the trajectory remote from the Earth is (a) a parabola; (b) an ellipse; (c) an hyperbola. 127. As a comet or spacecraft flies by a planet, its planetocentric velocity vector is changed in direction but not in magnitude. Analyze the dynamics of such an encounter and show how a net change in heliocentric kinetic energy of the comet or spacecraft can occur despite the fact that the planet's gravitational field is a conservative one.

Page 27 189. The planet Mercury as observed from the Earth never appears at an angle greater than about 28 degrees from the Sun. What is Mercury's greatest distance from the Sun? 190.
