Astronomy For Dummies

Can you hear a meteorite?

OK, strange question....Last night, I heard this subtle but pronounced "rumble". I couldn't tell where it was coming from (outside?), but I have notoriously bad hearing so I'm not surprised (thanks iPod!).

To my surprise, I read in the paper today that a meteorite pretty much passed right over where I live around the same time.

Co-incidence? Or not?

Any astronomy experts opinions greatly appreciated for this "astronomy dummy"! ;)

Thanks!


A meteor traveling faster than the speed of sound can produce a sonic boom, that is probably what you heard. It can produce a sound when it explodes in the atmosphere, or strikes the earth.
