Per·i·gee
/ˈpɛrɪˌdʒi/
A trajectory's closest point to the Earth.
Perigee represents the point in an orbital path where a celestial body reaches its minimum distance from Earth. This astronomical concept is particularly significant in astrology when considering the Moon's influence, as the Moon's perigee occurs approximately once per month during its elliptical orbit around Earth. The term is also applicable to artificial satellites and other celestial objects that orbit Earth. Understanding perigee helps astrology students appreciate the varying intensities of planetary influences throughout orbital cycles, as closer proximity traditionally correlates with stronger astrological effects in various interpretive systems.
