Petavius (177 km), is a large crater, located southeast of Mare Fecunditatis and has 3.4 km in depth. Attached to the northwest edge is the smaller crater Wrottesley (57 km). At southeast are Palitzsch (41 km), Vallis Palitzsch (a monthly valley near the eastern edge of Petavius that has a distance of about 110 km.), And Hase (83 km).
Petavius's outer wall is unusually large relative to its diameter, and displays a double rim along the southern and western sides. The convex crater floor was resurfaced by lava flows, and displays a system of trenches called Rima Petavius.
Central high mountains are a prominent formation with multiple peaks, which are reaching 1.7 km above the floor. A deep fracture goes from the peaks to the south-western edge of the crater.
The most favorable time to observe this crater through a telescope is when the Moon is only three days. From the fourth day, the crater is almost devoid of shade.
