almost satellite/telescope shaped but was either very large or very close. flew soundlessly and smoothly, rotated as it went

it was dark out, the object looked like some sort of satellite/telescope but it was really close. it was bigger than the size of a med flight helicopter when it’s flying fairly close to the ground. it didn’t make any noise, and rotated as it moved smoothly across the sky. i didn’t think it would be a satellite unless it was really, really large because typically satellites look more like a small dot moving smoothly across the sky. this moved smoothly but it was bigger and up close. it was a different color than the sky which was what allowed me to see it, but the object was still dark in color. rough details of shape are attached in the picture. also i checked the ISS position and it was nowhere near my location.
