Hommel (125 km.) is a lunar crater located in the south-east of the moon, in a region that is deeply affected by impacts, with many notable craters.Crater Pitiscus is near,in the the southwest; Nearch on north and Vlacq is almost attached to the northwest side of Hommel.Rosenberger is above Vlacq. Hommel is about 120 kilometers in diameter and its walls reach heights of 2,800 meters. It dates from pre-nectarian,some 4.55 - 3.92 billion years ago.
Hommel crater shows a number of smaller but still considerable craters: Hommel C overlaps the edge of south-east of Hommel, in the north-west is Hommel A. Hommel D is on the north-east Hommel's interior floor,and next to it is Hommel P .
The name comes from Johann Hommel (1518-1562) who was a German astronomer and mathematician.
Pitiscus (82 km.) is a crater which lies south-west of the crater Hommel. His form is roughly circular. Inside walls are still terraces, although they are rounded due to erosion.
The name is from Bartholomaeus Pitiscus (also Barthelemy, Bartholomeo, 24.08.1561-02.07.1613) which was a trigonometrist, astronomer and teolog.He invented the first trigonometry.
