The moon appears 30 percent brighter at perigee because it is 50,000 kilometers closer to Earth
The moon undergoes a dramatic transformation during its closest orbital approach, appearing significantly larger and casting thirty percent more light onto the Earth's surface than when it is furthest away.
When the Moon reaches its perigee at approximately 356,500 kilometers from Earth, it sits 50,000 kilometers closer than at its furthest point.
