Question

A few months ago I saw abig object next to the moon Not sure if NASA had a satellite next to it or not nor do I know how big some thing needs to be next to the moon to see it on earth with the naked eye.

Answer 1

That depends on how far away it was.  And it's really hard to judge distances to stuff in the sky.  It could have been an airplane a few miles up - but if it was actually next to the Moon and you saw it, it would have been the size of a Texas.  Believe me, you wouldn't have been the only one to see that.
