Eponym	David Fabricius

Fabricius is a lunar impact crater that is located within the northeast part of the walled plain named Janssen. Attached to the north-northwest rim is the slightly larger crater Metius.^[3]^: 114

The crater is 78 kilometers in diameter and 2,500 meters deep. It dates from the Eratosthenian period of the lunar geologic timescale, 3.2 to 1.1 billion years ago.^[2] Fabricius has multiple central peaks that rise to 0.8 km, with a rugged rise to the northwest running north–south. The infrared spectrum of pure crystalline plagioclase has been identified on these rises.^[4] The rim is lumpy and somewhat distended, most noticeably to the southwest and south.^[5]

This crater is named after Dutch astronomer David Fabricius (1564-1617). Its designation was formally adopted by the International Astronomical Union in 1935.^[1]

Satellite craters

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.
