What Is the Minimum Size of a Carbonaceous Condurite?

If you have a metal rich asteroid, meteoroid coming through the atmosphere, it's going to survive the atmosphere a whole lot easier. So if you want that giant, single divot in your yard, you need a big old metal meteorite. You want a carbonaceous condrite. And so when you get a many meter across condurite, you can end up with bowling ball sized chunks spread over. Well, there is a really cool one back in 19 69 that came in and exploded over the chawan desert, and left tons upon tons of debris for folks to go pick up and do research on.
