It followed us during half of our orbit. We observed it on the light side, and when we entered the shadow side, it disappeared completely. It was an engineered structure, made from some type of metal, approximately 40 meters long with inner hulls. The object was narrow here and wider here, and inside there were openings. Some places had projections like small wings. The object stayed very close to us. We photographed it, and our photos showed it to be 23 to 28 meters away.
