Astronomy Event Definitions:
Apogee: point in the Moon's orbit when it is farthest from Earth.
Conjunction: Occurs when two or more bodies appear close together in the sky.
Elongation: is the apparent angular separation of an object from the Sun.
Inferior conjunction: When planet Mercury or Venus pass between the Sun and the Earth.
Occultation: Passage of one object in front of a smaller one, thus obscuring all or part of the background object from view.
Opposition: When a planet farther from the Sun than Earth appears opposite the Sun in the sky. This is the best time to observe a planet.
Perigee: point in the Moon's orbit when it is nearest to Earth.
Stationary: Object appears motionless in the sky due to the turning point between its direct and retrograde motion.
