PDF document and a MATLAB script named pevents.m that can be used to compute interesting orbital events of the planets of our solar system. Using a combination of one-dimensional minimization and root-finding, the pevents MATLAB script computes the following heliocentric characteristics of planetary orbital motion.
• aphelion and perihelion of a planet
• nodal crossings of a planet
• closest approach distance between two planets
• minimum angular separation between two planets
