Metallic spinning object twinkling in the sun. Spinning consistently with what looked like lights as well.

An object was crossing the sky in a seeming straight line and consistent slowish speed (a plane flew lower and went much faster). The sun was reflecting off the object so it was bright but it was spinning so it was twinkling. No sound. A plane flew under nearby it much faster and louder. I noticed it on the horizon and watched it cross across the sky above me for at least 5 minutes. Took a cell phone video which also seems to show it was spinning. No spoke or trail behind it. Thought it may be a balloon but appeared higher than the plane and also would have had to be very large to be visible from there. Also it was at a consistent speed and spin, not appearing to be in the wind.
