Constant apparent size can sound like support for a nearby object staying at a fixed height overhead.
Debunk
The Moon's Near-Constant Size Proves It Is Local
Because the Moon looks about the same size, it must be a nearby local light rather than a distant body.
Why It Sounds Convincing
Calculation or Model
A genuinely nearby Moon moving around above a flat plane should show much stronger daily angular-size change than the modest variation actually observed in the real Moon's orbit.
Proof and Observation
- The Moon does not dramatically enlarge and shrink through one night.
- Observed lunar size variation is modest and linked to orbital distance, not daily overhead travel.
- Phase, landmark identity, and orientation still remain coherent with one distant Moon model.
Graphic
Compare the expected angular-size swing of a local Moon with the much smaller variation of the observed Moon.
Perigee–apogee variation stays small; a nearby lamp would swing far more.

Assumptions
- The claim must fit simultaneous observations at multiple latitudes and longitudes.
- Standard astronomical geometry is used as the comparison model.
- One explanation has to fit timing, angles, and visibility together instead of case by case.

What Would Falsify This Page
A repeatable observation or model that matched the claim while contradicting the page’s stated assumptions would count against this page.
Sources
- External source links will be added before final release: This debunk is still in beta, so the source list is currently a placeholder.
Conclusion
Near-constant lunar size is a problem for a local Moon, not support for it.
