Low, hovering globe of light in Mechanicsburg, PA

I was on my smoke break at work, and I was walking towards the parking lot from our office building and I looked up at the sky like I usually do to see if I could see any constellations. The sky was extremely clear and it looked like EVERY constellation was visible. So as I scanned the night sky I started to look towards the horizon and that is when I focused on what looked like a small round ball of clear thick/heavy glass in the air, about twice the height of a normal street light from the ground. I noticed that there were no street lights and no "outer" craft carrying the sphere (like a helicopter or something like that) the light just "went out". It was far too low to be a light from a craft or a shooting star. It was literally so low you would have thought someone was on one of those utility trucks fixing a power line. It made absolutely no noise, and was moving very slowly.
