Hi, Susan!
It's not an asteroid, no matter what the "scientists" are claiming. I've also been wondering about this object ever since I downloaded the pic when it was first published.
The shape is too symmetrical. Symmetry rarely happens in nature.
I truly believe this to be some sort of manufactered object.
Is it a manned craft? That's hard to say without better resolution.
It could be a probe of extra-solar origin.
Whatever it is, I truly hope the government will be upfront with us and allow pictures with better resolution to make their way to where we can check them out!
Let's wait and see if they have the cajones to be honest for a change!
