Frozen UFO in the sky

Long Description of Sighting Report
I was looking out back from my home and noticed this white/silver round object floating near cloud level. The object didn’t make any sound and just seemed to be hovering there. It may have moved a few feet, but not very far. I was not sure what this object was so I grabbed my camera and video taped it for about 4 minutes. It was exciting to see, but I could not figure out what it was.

Throughout the video shows that the UFO is stationary, it is not a balloon or a helicopter.
