Near the great lunar crater Petavius ​​with diameter of 177 km are smaller ones like Wrottesley (57 km), Hase (83 km), Palitzsch (41 km), and Vallis Palitzsch (110 km), Legendre (79 km), which is in darkness in these photos, and Snellius (83 km). North of Petavius ​​is Mare Fecunditatis.

Wrottesley (57 km), lies on the northwest edge of the crater Petavius, and the southeastern edge of Mare Fecunditatis and has a depth of 2.3 km.
    This crater has a circular shape with a slight inward bulge to the south and a system of terraces that line the interior walls. The interior has almost no features, except for a central peak, which rises in the middle of the crater.

       Hase (83 km), lies southwest of Petavius ​​and Vallis Palitzsch and Palitzsch are attached to the edge of the northeast.
Crater rim was damaged and eroded by a long history of subsequent impacts. The most important satellite crater of Hase is Hase D (56 km), a crater that is located at the southern edge. Hase D is definitely deeper than Hase, because as you see in the picture, you can't see the floor of Hase D. The crater floor is in total darkness.

       Palitzsch (41 km), and Vallis Palitzsch (110 km), lies south-east of Petavius. Crater Legendre is located southeast of Palitzsch.
 Northeast end of Palitzsch forms the southern edge of Vallis Palitzsch, a lunar valley following the eastern edge of Petavius , ​​a distance of about 110 km. Crater rim is easily confused with the valley itself.

      Legendre (79 km), is a crater with a depth of 2.7 km. Onli the crater edge can be seen in these pictures. The floor is steeped in darkness, and therefore I will speak only on the edge, which is eroded by other small craters,  on the inside and the outside of it.
       Adams is a 66 km crater in diameter and 2 km deep. It was named in honor of three astronomers John Couch Adams, Walter Sydney Adams and Charles Hitchcock Adams.
