Janssen is a huge 115 mile diameter damaged
crater, which appears to be six sided. The inside floor is very
chaotic, with a small rille cutting a quarter circle inside from
wall to wall. (Rimae Janssen). On the lower left of the inside
of Janssen is a beautifully formed terraced crater Fabricius,
some 47 miles in diameter. Inside are some very stunning linear
mountain chains, seen well in this reproduction.
