One monumental paper (Robbins 2019) manually counts craters in high-res imaging, finding 1.3 million craters with diameters > 1km, already more than the ~1 million potholes in the UK with diameters less <1m.

A reckless extrapolation of the count down to ~1m lunar craters and you're in the region of 10's of billions to 10's of trillions of potholes on moon. Hoping this ends all election potholes > craters statements to bed! 🧪🔭

Huge 🙏 to @planet4589.bsky.social for e-help and advice on this Q.

Ah, but what is the minimum size of a lunar crater and of a British pothole? Choose your data carefully and you can make the statistics tell you most anything you want. (That's the serious point of this otherwise silly skeet.) Otherwise, you may wish to go to Hell! Norway or Moon - your choice.

"1 million potholes in the UK with diameters less <1m."

Extrapolated from the number in Blackburn, Lancashire there were 2M potholes in 1967. Ref: en.wikipedia.org/wiki/A_Day_i...

Based on my observations, there must be many more than that now.
