Geological Chronicle

Hase lies in the rugged southeast part of the Moon, south-southwest of the walled plain Petavius. Two features attach to its northeastern rim: Palitzsch and Vallis Palitzsch. Its registry namesake is Johann Matthias, a German mathematician (1684–1742).

A long history of later impacts has damaged and eroded the rim. The comparably sized crater Hase D overlies the southern rim, leaving only a low rim between the formations. Hase A lies inside Hase near the irregular northern rim, and the rest of the floor is rough and irregular.

Southeast of Hase D, a system of linear rilles called Rimae Hase extends northwest. Its extension transects the western parts of Hase and Hase D.

Chronology & Exploration

1. Undated Later impacts erode the rim

   A long history of subsequent impacts has damaged and eroded Hase’s rim.

2. Undated Hase D overlies the southern rim

   The comparably sized crater Hase D lies across the southern rim, leaving a low rim between the formations.

3. Undated Rimae Hase crosses both craters

   The rilles’ northwestern extension transects the western parts of Hase and Hase D.
