the large asteroid has 111.65km and a rotational speed of 8.64h / r. Assumed spectral class dark D and C. When photographed, the asteroid was at a distance of 4,773au and closest on November 9, 2021 to 4,215au. In Figure 7 came a satellite line that hit an asteroid so it had to be removed from the stack.
