Legend:
-Perihelion-position in the orbit of a planet closest to the Sun.
-Aphelion - position in the orbit of a planet farthest from the Sun.
-Perigee -  the position of the Moon closest to Earth.
-Apogee -  the position of the Moon farthest to Earth.
-Inferior Conjunction - Mercury or Venus passing between the Earth and Sun.
-Superior Conjunction - Mercury or Venus passes on the opposite side of the Sun from Earth.
-Greatest elongation - elongation is the angle between the Sun and a planet as seen from Earth, during eastern elongation (E), the planet appears as an evening star, during western elongation (W), the planet appears as a morning star.
-Opposition - position in the orbit of a planet when opposites the Sun as seen from Earth.

-Conjunction - position in the orbit of a planet when appears closer to the Sun as seen from Earth.
-Occultation - Moon occults or eclipses a star or a planet.
-Ascending Node - the point where a planet passes from the southern to the northern part of its orbit.
-Descending Node - the point where a planet passes from the northern to the southern side of its
