PERILUNE Meaning and
Definition
-
Perilune refers to the point in the orbit of a satellite or spacecraft when it is at its closest distance to the moon. The term is specific to lunar missions or spaceflights involving lunar orbits.
In the field of astronomy and astrodynamics, the moon's gravity significantly affects the trajectory and behavior of objects in space. During an orbit around the moon, the satellite or spacecraft experiences two distinct points: the apolune, which is the highest point farthest from the moon, and the perilune, the lowest point closest to the moon.
The perilune is a critical aspect of lunar missions as it is the stage when spacecraft are most vulnerable to potential hazards and challenges. Due to the extreme gravitational forces exerted by the moon at this point, accurate navigation and control are crucial. Additionally, the perilune often determines the trajectory for subsequent orbits or mission objectives, making it an essential focus for mission planning and execution.
Understanding the perilune assists mission designers, engineers, and astronauts in ensuring the safety and success of lunar missions. It allows for effective orbiting strategies, precise measurements, data collection, and enables the fulfillment of mission objectives with greater accuracy.
In summary, perilune refers to the point of closest approach to the moon in a satellite or spacecraft's lunar orbit. It plays a critical role in mission planning, navigation, and achievement of objectives during lunar missions.

Etymology of PERILUNE
The word "perilune" is derived from two components: "peri-" and "lune".
The prefix "peri-" comes from the Greek word "peri", meaning "around" or "near". It is commonly used in various scientific terms to indicate proximity or rotation around a particular object.
"Lune" originated from the Latin word "luna", which means "moon". It is connected to the Latin name for the moon, "luna". "Lune" is also used in astronomical and celestial contexts to refer to the moon or moon-like shapes.
Therefore, combining "peri-" and "lune", the term "perilune" refers to the specific point in an orbit around the moon when a satellite or spacecraft is closest to the moon's surface.
