Exam 4: Gravitation and the Waltz of the Planets

If an object is launched radially away from a planet, it will continue to follow a straight path. If it is not launched radially, however, its path will be a curve. If the launch speed is equal to the escape speed, (assuming it reaches an orbit) this curve will be a(an):
