("nearby today" relatively, of course.) - - - - edit to add: wow you sure touched a nerve, eh? I dunno what nerve exactly, but I agree with your sib comment about how it would be great if your meatier comments got such engagement. FWIW in my personal estimation doing something (or not) about asteroid detection and mitigation (if possible) is one of the measures of the maturity of a civilization (that lives on the congealed scum on the surface of a blob of magma orbiting a puddle of hydrogen in a region of space filled with rocks!) It's wild that just a couple of centuries ago (less!) the very idea of rocks falling out of the sky was unthinkable (like UFOs or bigfoot.)
