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.
