It's the moon! Plain and simple. It isn't planet x it isn't a meteor come to crash on earth. It's just the moon, the mice are up there eating away as we speak.

And the Moon isn't 1st quarter - it's currently in it's second quarter, nearly full (full moon this Saturday)

It ain't planet x, too big. i believe its the moon, but talk is cheap. think of the logic though, what else would be that big and bright next to us??
