‘Is the Moon a hollowed-out spaceship sent to orbit our earth in the remote prehistoric past?’ —Don Wilson, “Our Mysterious Spaceship Moon”

The moon is the most dominant feature in our night sky, inspiring both wonder and myth since antiquity. While the past few decades have offered new understanding about many lunar mysteries, a great number of unanswered questions still surround our only natural satellite. We’ve come to rely on this white planetoid, which ceaselessly orbits our planet every 28 days, as an important part of our natural world. Yet when we begin to analyze the physical qualities of our familiar neighbor, many details suggest that the moon might not be that natural at all.

A manufactured moon?! Where did this absurd theory originate? First posited in the 1960s by Russian scientists Mijail Vasin and Alexander Sherbakov—and later endorsed by investigators and colleagues intrigued by this hypothesis—the idea contains eight postulate principles analyzing some of the most curious characteristics of our lunar companion. Below is a brief summary of these observations.

First Lunar Mystery: Large Satellite, Small Planet

Compared to other planets in our solar system, both the orbit path and size of our moon turns out to be a fairly considerable anomaly. Other planets, of course, have moons too. But with their weaker gravitational influence, the smaller planets —like Mercury, Venus and Pluto—do not. Similarly sized Earth, on the other hand, carries a moon one-quarter its size. Compare this with the immense Jupiter or Saturn, which have several comparatively tiny satellites (Jupiter’s moons measure about 1/80th the size of the large planet), and our moon seems to be a rather rare cosmic occurrence.

Another interesting detail is the moon’s distance from Earth—close enough so that it appears equal in size to our sun. This curious coincidence is most apparent during total solar eclipses, where the moon completely covers our closest star.

Finally, with a nearly perfect circular orbit, the moon does not behave like other satellites that tend toward a more elliptical path.

Second Lunar Mystery: Unlikely Curvature

The gravitational center of the moon is nearly 6,000 feet closer to Earth than its geometric center. With such a significant discrepancy, scientists remain unable to explain how the moon manages to maintain its nearly perfect circular orbit without wobbling.

Third Lunar Mystery: Craters

Think of photos illustrating the surface of the moon and you’re sure to imagine a world marked with craters. The vast majority of spatial bodies hurling toward Earth’s surface are either completely dissolved or significantly diminished due to several miles of our protective atmosphere. Without such an atmosphere, the moon does not appear to fare as well. Yet when you consider that the depths of these craters are remarkably shallow in comparison to their circumference, it suggests that the moon possesses an extremely resistant material that prevents deeper penetration. Even craters over 180 miles in diameter do not go deeper than 4 miles. If the moon were merely a homogeneous hunk of rock, it is estimated that there should exist craters of at least four to five times as deep.

Vasin and Sherbakov proposed that the lunar crust was perhaps made of a titanium frame. In fact, it has been verified that the lunar crust possess an extraordinary level of titanium. The layer of titanium estimated by the Soviet team is nearly 20 miles thick.

Fourth Lunar Mystery: Lunar Oceans

How did the so-called lunar oceans form? These gigantic extensions are believed to be hardened lava said to have come from the moon’s interior due to an impacting meteorite. While this theory can be easily explained with regard to a warm planet having a molten interior, many say that the moon is more likely to have always been a cold body.

Fifth Lunar Mystery: Gravitational Inconsistency

The gravitational attraction on the moon is not uniform. The crew onboard Apollo VIII noticed their craft taking abrupt dips when flying near the satellite’s ocean areas. At these sites, gravity seems to mysteriously exhibit a greater influence.

Sixth Lunar Mystery: Geographical Asymmetry

On the moon’s far side (the side that can’t be seen from Earth), we have found many craters, mountains, and geographical upheaval. Yet the side facing Earth is where we find the great majority of the satellite’s oceans. Why are 80 percent of the lunar oceans found only on one side of the moon?
