PROBLEM:1.209


A planet A moves along an elliptical orbit around the Sun. At the moment when it was at the distance r0 from the Sun its velo­city was equal to v0 and the angle between the radius vector r0 and the velocity vector v0 was equal to a. Find the maximum and mini­mum distances that will separate this planet from the Sun during its orbital motion.
