Problem
Imagine there is a comet that threatens the Earth once a generation, just when it is in the perihelion. What is the distance between the Earth and such a comet when the comet is in its aphelion? What is the length of the semi-major axis and the orbital eccentricity of the comet's trajectory? Do not consider gravitational influences other than from the Sun, and assume that one generation is g=20years.
