Why do people with two different countries see the moon upside down?

The Moon appears “upside down” to people in opposite hemispheres because of the way we perceive it from different perspectives on Earth.

Key Explanation why this happened?

Earth’s Curvature:
- The Earth is a sphere, and people in different hemispheres (e.g., the Northern and Southern Hemispheres) are oriented differently relative to the Moon.
- For example, someone in the Northern Hemisphere views the Moon with their “top” (north pole) closer to the celestial north, while someone in the Southern Hemisphere is essentially viewing it from an inverted angle.
Orientation of the Viewer:
- Imagine the Moon as a fixed object in the sky. When you move to the other hemisphere, you’re essentially flipping your orientation relative to that fixed object.
- This is similar to how a painting hung on a ceiling would appear “upside down” if you were lying on the floor looking at it.
The Moon’s Position in the Sky:
- The Moon orbits Earth along the ecliptic plane, which is tilted relative to Earth’s equator. This means that the Moon’s position and orientation appear different depending on where you are standing on Earth’s surface.

In short, the “upside-down” appearance is a matter of perspective based on the viewer’s location on Earth’s curved surface.
