Principle purpose of this lecture is to present on Examples of Planetary Events. Some events are; Conjunctions: Two objects closest from Earth’s point of view. Stationary: When the ecliptic longitude (sometimes RA) do not change. Greatest elongation: Approximately the best time for observing inferior planets. For Mars, opposition occurs approximately every 2.14 year. Due to higher orbital eccentricity (0.093) and smaller semi-major axis (1.52 AU), the Earth-Mars distance varies between 0.66 and 0.38 AU (1.52×(1 ± 0.093)–1), giving large size and brightness variation at opposition.
