Detailed explanation-1: -Complete step by step answer: The revolution of the moon around the earth is due to gravitational force. The sun also exerts gravitational force on the moon, which is almost twice as large as the gravitational force of earth.
Detailed explanation-2: -The Moon illusion is the name for this trick our brains play on us. Photographs prove that the Moon is the same width near the horizon as when it’s high in the sky, but that’s not what we perceive with our eyes. Thus it’s an illusion rooted in the way our brains process visual information.
Detailed explanation-3: -The Earth interacts with the Moon by the virtue of its gravitational force. Without gravitation acting on the moon, it would fly away. Hence, gravitation is responsible for revolution of moon about earth.
Detailed explanation-4: -Although the sun is 27 million times more massive than the moon, it is 390 times further away from the Earth than the moon.
