Hagecius (crater)

Hagecius

Diameter	76 km
Depth	Unknown
Colongitude	316° at sunrise
Eponym	Thaddaeus Hagecius

Hagecius is a lunar impact crater in the southeastern part of the Moon's near side. This crater forms a triangular formation with the craters Rosenberger to the north-northwest and Nearch to the west-northwest. Like both of these craters, Hagecius has undergone erosion from subsequent impacts, and its outer rim is worn and irregular. The southeastern rim in particular is overlaid by three smaller craters designated Hagecius C, B, and G.

The interior floor of Hagecius is a level plain with no significant rises. There is a small craterlet to the northwest of the midpoint, and a few tiny craterlets marking the southeastern half of the floor. About a third of the interior floor on this side is also overlaid by the outer ramparts of the three satellite craters mentioned above.

To the northeast of Hagecius is the crater Biela, a younger formation with more distinctive features.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hagecius.
