Tycho Crater

The Tycho Crater is a crater on the Moon having the diameter of 85 km (53 miles). It is too small to recognize using the naked eye. However, it lies on a bright colored highland that can be mistaken as the crater itself. The crater also has an extensive ray system, which was from the ejected materials when the crater was formed.

Flat-Earthers claimed the visibility of the Tycho Crater proves the Moon is not that far. They are wrong. We cannot see the Tycho Crater using the naked eye. What is visible is the highland it lies on or its extensive ray system.

Sunlit Objects and Visibility of Stars

Generally, sunlit objects are far brighter than any stars. It is the reason stars are not visible in a lot of photographs showing sunlit objects unless the objects are overexposed and made much brighter than the correct exposure.

Flat-Earthers take the lack of stars in photographs as evidence of misconduct. They are wrong. If the primary object in the picture is sunlit, then in most cases, stars will not be visible.

The Dark Sky on the Lunar Daytime

On Earth, daylight sky is glowing in bright blue due to Rayleigh scattering. Sunlight is scattered in every direction by the oxygen and nitrogen molecules in Earth’s atmosphere.

Such the phenomenon does not happen on the Moon, causing the dark sky of the Moon. Flat-Earthers claim that the dark sky of the Moon captured by photos and videos taken from the Moon are “proof” there is misconduct. They are wrong. Just because Earth’s sky is bright blue, it does not mean it will be like that on the Moon and other planets.

Lunar Libration

Featured Video Play Icon

The Moon is tidally locked. Half of the Moon is always facing the Earth. However, due to libration, we can take a glimpse of areas of the moon that are not always visible.

Flat-Earthers invented many “scenarios” to “explain” how the so many lunar-related phenomena can happen on the flat Earth model. Some of these “explanations” include “transparent Moon”, “hemisphere-shaped Moon”, “flat circular Moon”, etc. Lunar libration rules out the majority, if not all, of these “explanations.”

Lunar Craters

At any time, the Sun illuminates one half of the Moon and the other half dark. The phase of the Moon is the shape of the sunlit portion of the Moon as viewed by observers on Earth.

The phase of the Moon can never be adequately explained using the flat Earth model. To deal with this inconsistency in their theory, some perpetrators of flat Earth invented an ‘explanation’ that the phase of the Moon is not caused by sunlight. They are wrong. We can observe the Moon very carefully using telescopes of high-zoom cameras, and it will be evident how the lunar craters are lit. And this can only happen if the Moon is sunlit.

The Orientation of the Moon

The Moon looks practically identical from everywhere on Earth because the Moon is very far relative to the distance between observers on Earth. However, its orientation is different when observed from the various locations across the globe. The reason is that the Earth is a sphere: the different observers are not on the same plane and have the different orientations themselves.

Some Flat-Earthers have spatial awareness difficulties and present the difference of the orientation of the moon as ‘evidence’ of a flat Earth. They are wrong. If in their model the Moon is close, we should be able to see the different face of the moon on the different location on Earth. But we clearly don’t.

Total Lunar Eclipse, Drawn to Scale

Any diagram showing two or more celestial bodies is almost never drawn in the correct scale. The reason is that in most cases, any two celestial bodies are spaced too far away relative to their sizes. It is just not possible to draw them in the correct scale and still effectively describes what we want to explain. We don’t have much choice other than drawing them not to scale.

The perpetrators of flat-Earth disseminate the allegations that the diagrams were drawn not to scale because of evil intentions, and not because of legitimate technical reasons. Some people don’t understand this and fell victim to flat-Earth indoctrination.

Phases and Side of the Moon

In the real world, the Moon is spherical. It doesn’t emit its own light; it gets its light from the Sun. The Moon is tidally locked, causing one side of it to be permanently turned towards the Earth. The lunar phase occurs because of the change in the position of  Sun-Earth-Moon with respect to each other.

Any flat-Earth model fails to explain many Moon-related phenomena. Flat-Earthers who insist on defending their misguided flat-Earth concept at all costs are forced to invent many “explanations” on how Moon-related events might happen on a flat-Earth.

Simple observation tells us that we always see the same side of the Moon, but the phase changes in a month-long cycle. These facts rule out the majority of the “explanations” invented out of thin air by flat-Earthers, including the “Moon emits its own light”, “half-sphere Moon” and the “transparent Moon” explanations.

The Moon in Daytime and the ‘Transparent Moon’ Misconception

Earth’s atmosphere scatters sunlight in every direction. Bluish colors are scattered stronger than reddish tones. As a result, the sky is glowing in bright blue during the day. The phenomenon is called the Rayleigh scattering.

Sometimes the Moon is visible during the day. The bright part of the Moon is bright because it is lit by the sunlight. On the other hand, its dark part does not receive sunlight, and thus barely emit any light. Because of these reasons, the dark part of the Moon is dominated by the blue color of the sky.

The Phase of the Moon and a Ball

The phases of the Moon depends on the position of the Moon relative to the Earth and the Sun. They occur because the Moon is spherical & lit by sunlight and that the Sun is very far away. Both imply that the Earth is spherical too.

The phases of the Moon according to observation cannot be explained in any flat-Earth model. Flat-Earthers had to invent various explanations to explain how the lunar phases can happen in the flat-Earth model. None can explain how a ball has the same phase as the Moon when seen from the same direction as we see the Moon.

Apollo Mission Profile

The Apollo missions really happened and humans have actually visited the Moon. If someone fell victim to the flat-Earth conspiracy, then it would imply that they also fell victim to the Apollo moon landing conspiracy. But they are wrong. 

Someone usually fell for the moon landing conspiracy theory because of emotional appeals and confirmation bias, but also because of their ignorance of the Apollo mission profile itself.

The following is a very brief description of the Apollo mission profile, numbered according to the numbers in the illustration.

The Illusion of Clouds Appearing ‘Behind’ the Sun or the Moon

Sometimes, we can see clouds appearing as if they are behind the Sun or the Moon. Obviously, this is merely an illusion. But some flat-Earthers regard this as ‘evidence’ that the Sun and the Moon are close and apparently closer than some clouds. They are wrong.
