Long Description of Sighting Report

I went out my back yard to a field that is an old golf course. I had my camera with me as I usually do. I noticed a bright white round ball in the sky. I began shooting pictures and then took some video footage of this object as it went from right to left (west to east). I would estimate this object as being over a mile away. I continued taping until the object could not be seen as it passed behind the trees. There was no noise that i could detect. It also looked to be shimmering, or reflective.
