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. Greatest elongation is best for viewing as it is at it's highest point above the horizon.
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 as it is closet to the Earth.
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.
Blue moon: Second full moon to occur in a calendar month.
