Fabricius is a lunar impact crater that is located within the northeast part of the walled plain Janssen. Attached to the north-northwest rim is the slightly larger crater Metius. Fabricius has multiple central peaks that rise to 0.8 km, with a rugged rise to the northwest running north–south. The rim is lumpy and somewhat distended, most noticeably to the southwest and south.[1] It is 78 kilometers in diameter and 2,500 meters deep. It is from the Eratosthenian period, 3.2 to 1.1 billion years ago.[2] It is named after David Fabricius, a 16th-century German astronomer.[3]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Fabricius.[4]
