Usage: Planets.py Planet [Planet ...] year [year ...]
Planets are Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune

Usage: Planets.py all year [year ...]
       produces output for all seven planets
       year must be not less than -4713 (start of Julian Day counting)

Usage: Planets.py verify
       runs Meeus's benchmark cases

Planet Events are:
       Superior Conjunction, planet passes behind the Sun
                the angle between Sun and planet has a minimum
       Inferior Conjunction, planet passes between Sun and Earth
                this is only possible for Mercury and Venus
       Opposition, planet is opposite to Sun
                this applies to the outer planets
       Eastern Elongation (Venus, Mercury): maximum angle between
                Sun and planet, planet visible in the evening
       Western Elongation (Venus, Mercury): maximum angle between
                Sun and planet, planet visible in the morning
