Unknown
Young craters on the Moon as Byrgius (87 km), and larger old craters, have large deposits of lava material within and around them. Initially thought to be of volcanic origin, but these deposits are now known to be from the high pressure shock and melting of materials on the impact area. Melted deposits from impacts are recognized as streams and ponds.
Byrgius, is located on the western edge of the Moon. As a mark, looking at the whole Moon, I think is right between the two craters Grimaldi on north, and Schickard on south.
Byrgius's edge is eroded, with Byrgius A (19 km) on the east and Byrgius D (27 km), located in north-western edge. The floor is relatively flat and non-distinctive because of small craters on it. Byrgius A has a ray system, which extends over 400 kilometers. This feature makes Byrgius A more interesting than Byrgius.
Crater name comes from Jost Burgi, or Joost, or Jobst Burgi (February 28, 1552, Lichtensteig, Switzerland - January 31, 1632), who produced and astronomical instruments.
