This is a common question that many people have, especially when they are riding in a car or walking at night.
The reason why the moon seems to follow you is because it is very far away compared to the objects on Earth that you pass by.
The moon is about 384,000 kilometers (238,900 miles) away from Earth, while the trees, buildings, and other things around you are only a few meters or kilometers away.
When you move, these nearby objects change their position relative to you very quickly, but the moon does not. It stays in the same place in the sky, no matter how far you travel. This creates an illusion that the moon is moving along with you, or following you.
The sight is not caused by the moon physically following the observer, but rather by the brain’s perception of the moon’s size and distance.
This phenomenon of the moon appearing to follow an observer is known as the “moon illusion.” This optical illusion occurs when the moon is near the horizon and is perceived to be larger than when it is higher in the sky.
in scientific terms, the main reasons for the moon illusion include:
Perception of Size and Distance
When the moon is near the horizon, it is viewed in relation to familiar objects such as trees, buildings, or mountains, which creates a perception that the moon is larger than when it is higher in the sky
The brain compares the size of the moon to the size of objects on the horizon, leading to the illusion that the moon is larger than it actually is.
Atmospheric conditions near the horizon, such as dust, haze, and moisture, can contribute to the illusion of the moon appearing larger and closer
When next you look and the moon appears to be following you, give the moon a smile!
