Hi all, I've read somewhere that at least 20% of our galaxy's stars have planets orbiting them? But what is the share if we include all kinds of rocky bodies? How likely is it that stars suck in everything without leaving any leftover material what so ever? I'm curious because the Drake equation seem to have a flaw in that it requires planets in order for life to form. Wouldn't all the required elements would also be available on smaller objects as well? The environmental conditions might not be as hospitable, but that's a separate question. Thanks as always!
