Coming back from evening walk back to the house, stopped to check mail...looked up and noticed 2 commercial planes high altitude and close together...thought that was strange. I pointed to show my wife and then she said what is that? Coming from the North at 10 o'clock was the sphere. I would estimate it was at an altitude of 1000 to 1500 feet... it appeared at that distance the size of a pencil eraser (bit smaller)... it appeared to be metallic as the sun was reflecting off of it. It made no sound, saw no wings. It never changed speed (which appeared to be 80 mph) and continued straight south until we could not visually see it anymore because of distance....
