UFO silverish color moving slow to the southwest

Hard to tell actual shape of the UFO. It was moving slow to the southwest. Did not hear any engine i.e. Jet or prop. It about 10 minutes to pass. I was coughing a softball team so I couldn't keep a constant eye on it my wife saw it first and told me about it. I thought it might be some type of drone or maybe a weather balloon but the shpae was not round but more cylinder but it was that far away that I could tell the actural shape, my wife said the same thing
