I took a look at this idea which seemed to be based on sketchy evidence. I used Google Earth to check Mars and the Moon. Visually inspections did not
offer any real evidence of anything unusual other than the difficulty of stitching images together in the polar regions.
So next I went to find out if there was ant known about an uneven distribution of craters on any of the planets or moons.
Introduction to Cratering Studies
The interpretation of Figure 5 is that the craters are indeed giving evidence of progressive loss of smaller craters -- an environment
different from the moon. Probably the agent is infill by windblown dust, which obliterates smaller craters.
Lunar Crater Stats Indicate Hidden Population of Asteroids
In the 80s and 90s astronomers noticed that the distribution of craters on these objects was asymmetric: they were more heavily cratered on
their leading hemispheres which makes sense since it seems obvious that these areas should be struck more often.
So it seems that the claims of more craters at the poles is not true at least for the moons of the solar system.
Asymmetric impacts of near-Earth asteroids on the Moon
From the abstract
Recent lunar crater studies have revealed an asymmetric distribution of rayed craters on the lunar surface. The asymmetry is related to the
synchronous rotation of the Moon: there is a higher density of rayed craters on the leading hemisphere compared with the trailing
hemisphere.
I thought you might be interested in reading this story.
How Young is the Lunar Crater Giordano Bruno?
About 30 years ago it was supposed that people saw the impact that formed this crater.
"Now there was a bright new moon, and as usual in that phase its horns were tilted toward the east and suddenly the upper horn split in two.
From the midpoint of this division a flaming torch sprang up, spewing out, over a considerable distance, fire, hot coals, and sparks. Meanwhile the
body of the moon, which was below, writhed ...[and] throbbed like a wounded snake."
This was written about events in 1178.
Is this the event that caused the crater on the moon? It's an interesting read and I won't provide the answer here.
