This entail that if you were stand on the Moon, you could easy blot out the entire Earth - every city, every mountain compass, and every ocean - with the tip of your pollex. This realization changes how we view geopolitical borders, which are wholly inconspicuous from that length.
| Perspective | Angular Size (Degrees) | Visual Control |
|---|---|---|
| Moon from Earth | ~0.5 degrees | Bright, night-defining |
| World from Moon | ~1.9 stage | Stunning, blue, fixed position |

Understanding how small is Earth from the Moon highlight the fact that there is no "backup" satellite visible within that contiguous field of prospect; there is only the diminutive, blue marble.
- The Blue Marble Effect: The realization that all human chronicle, warfare, and achievement have occurred on a midget speck.
- Absence of Borders: The impossibility of see lines drawn on function from the lunar surface.
- Isolation: The identification that Earth is a funny haven in a vast, dark expanse.
