The Moon Should Have More Craters, and the Reason is Shocking

It’s enough to take a good look at the Moon at night with your binoculars to realize that our natural satellite hasn’t been through any fairy tales with happy endings. The Moon’s surface is teeming with craters due to asteroid collisions.

If you’re asking yourself why doesn’t Earth have craters like the Moon, a simple explanation is that our natural satellite doesn’t have a protective atmosphere.

More early asteroid collisions than craters prove writes that the Moon has been through more asteroid collisions in the space object’s early stages than the surface shows nowadays.

But what could the explanation be? Why don’t we see more craters on the Moon’s surface? The explanation might shock you.


The new research proposes the scenario where the surface of the early Moon was a lot softer than it is nowadays. This likely happened due to a global ocean of magma covering the cosmic object in its early stages, similar to what happened on Earth long ago.

Katarina Miljkovic, who’s a planetary scientist at Curtin University in Australia, declared as quoted by

These large impact craters, often referred to as impact basins – formed during the lunar magma ocean solidification more than four billion years ago – should have produced different looking craters, in comparison to those formed later in geologic history.

Miljkovic also declared, as cited by the same publication:

The timeframe for the solidification of the lunar magma ocean varies significantly between different studies, but it could have been prolonged enough to experience some of the large impact bombardment history typical for the earliest periods of the Solar System evolution.

As the Moon ages and the surface cools, it becomes harder, and the bombardment imprints are a lot more noticeable by remote sensing.
