Re: [meteorite-list] Crater maker

When you talk about something as large as the K-T event, even defining "crater" gets a bit tough. The primary physical structure was probably around 150km in diameter. Given an impactor that was 10km in diameter, this doesn't fall far outside the 10:1 rule. At the other end of the range, you ha

Re: [meteorite-list] Crater maker

I would think that larger meteorites would have a larger ratio of crater:impactor size because they have a lower surface area to volume ratio so they would impact with a higher final velocity. So to make a crater, I'm sure you'd need an impactor much larger than 3 feet as the 10 to 1 ratio woul

Thanks to all who responded. Other than the 10 to 1 ratio, I pretty much thought the same as what most people stated. Here is what I did respond with: -- One "formula" in which I hold very little belief, is a ratio of 10 times the diameter of the impactor. This question has far to m

A good rule of thumb is that craters are roughly ten times larger than the impactor that created them. There is, of course, a wide range of variability here, depending on velocity and other factors. Small craters are very uncommon on the Earth because it is so difficult for small objects to arr
