PERIGEE Meaning and
Definition
-
Perigee is a term primarily used in astronomy to describe the point in the orbit of the moon or an artificial satellite where it is closest to the Earth. Derived from the Greek words "peri," meaning around or near, and "gee," which refers to the Earth, perigee represents the moment of closest approach between the celestial object and our planet.
When the moon or a satellite is at perigee, it is at its smallest distance from Earth within the particular orbit it revolves around. This distance can vary depending on several factors, including the shape and characteristics of the orbit itself. The opposite point in an orbit, where the object is furthest away from Earth, is referred to as "apogee."
Observing perigee is significant in the field of astronomy and satellite mission planning, as it affects various phenomena such as tides and gravitational forces. Additionally, perigee is a key consideration for astronomers and space agencies when studying the moon, analyzing its proximity to Earth during different periods to gain insights into various lunar processes and phenomena.
Overall, perigee is a critical term in celestial mechanics, allowing astronomers and scientists to track and predict the positioning and behavior of astronomical objects within their orbital paths around Earth.
