Close-up Shot of To Ngoc Van
Prominent near the center of the degraded crater To Ngoc Van is an irregularly shaped pit. Examples of pit-floor craters have been identified across Mercury's surface and are likely formed by past volcanic activity. To Ngoc Van was named in 2009 in honor of the 20th century Vietnamese painter.
