Chrome shape changing, stationary

While working out on my bench I looked up and saw a small object very high in altitude. I grabbed my binoculars and could see it better. Seemed to be changing shape as it reflected light in different ways. Rotating object looked round, then triangle, then square. Sometimes it looked like two. After a while it moved away at a slow speed, then disappeared. Then showed back up at original location. Its probably still sitting there as I couldn’t be out there all day. I had also seen the same thing a couple of days earlier but it blinked twice then disappeared before I could get my binoculars. This was no balloon or aircraft. Will be updating if seen again
