Australia ... Largest Asteroid/meteorite Crater?

[mn90403]

I've read this story a couple of times and I think the semantics of asteroid vs meteorite is probably a matter of size.  In any event, this mapping of a zone of impact says it is the largest known.  I'd say we need to check the oceans.

This structure is not too far from Northeast.  Maybe he can tell us more.

Meteorite is what's left (if anything) after the object comes to rest.  Before that it's a meteoroid.  Those can be either asteroids or comets.

The one they claim to have discovered (I assume it still needs to be confirmed) is indeed quite large.  The Chicxulub crater which is what remains from the object that wiped out the last of the dinosaurs is only about 1/3 the diameter (maybe 1/8 the area).  According to this list, not only is this new discovery potentially (by far) the largest earth astrobleme known but only about 10 or 11 are estimated to be older.

Pretty impressive if further study confirms what they are reporting.
