What Does PER Stand For?
PER stands for Perigee
PER, or Perigee, refers to the point in the orbit of an object where it is closest to the Earth. This term is commonly used in astronomy and orbital mechanics to describe the varying distances of satellites, moons, and other celestial bodies as they travel around the Earth, impacting gravitational forces and observable phenomena. Understanding perigee is essential for accurate orbital calculations, satellite positioning, and mission planning in space exploration.
