I don't know. I would have to say the object I have seen is exactly the same as all the ojects filmed around the world.
So it would have to be the one object wouldn't it?

What are the odds of exactly the same looking oject showing up everywhere, being different objects?

Now that being said it must be huge because it is a long way out and I mean, if it was already close or in our atmosphere it would have already collided with the earth.

So it is on its way in one would assume!
