Qi Baishi (crater)
Qi Baishi is a crater on Mercury. It has an asymmetric pattern of ejecta rays, which formed by an object travelling to the east or to the west and impacting Mercury's surface at a very low incidence angle. However, Qi Baishi crater is still roughly circular, which is in contrast to the elongated shape of neighboring Hovnatanian crater.
