I wonder how large it was before burning away a considerable amount of it's mass? Nickle Iron perhaps?
That's a good question.
It's strange that such a large object didn't make a crater.
@Ellatynemouth Mega tons from the picture,I wonder,was it moved? Was it discovered,any witness to it's arrival?
@Louise1920
From the article, it crashed thousands of years ago. So no modern witnesses.
@Ellatynemouth Sorry,should have read the article,still wonder about no crater. If I remember the Tunguska explosion in Siberia a very long time ago,was theorized as being either an anti matter reaction, or a spaceship,no one seems to know exactly what.
