Milichius (crater)
Milichius is a bowl-shaped lunar impact crater that is located in the northern part of the Mare Insularum. To the southeast is the slightly larger Hortensius, a similar formation.

The crater is named after 16th century German doctor, mathematician and astronomer Jacob Milich, Latinized as Milichius.[1]
Just to the west is a typical lunar dome designated Milichius Pi (π) that has a tiny craterlet at the peak. The narrow and sinuous Rima Milichius rille is located farther to the southwest, and follows a course running roughly north–south for 100 kilometers.
Satellite craters[edit]
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Milichius.
