What is the difference between Perigee and Apogee?
Quick Answer: Perigee is when the Moon is closest to Earth, and Apogee is when it is farthest away. These points change the Moon’s apparent size and brightness in the sky.
The Moon orbits Earth in an elliptical path, so its distance varies. At Perigee, the Moon is nearest, roughly 363,000 kilometers away, making it look bigger and brighter.
At Apogee, the Moon is farthest, about 405,000 kilometers away, so it appears smaller and dimmer. This changing distance affects tides too.
