(IAU Directions) HOMMEL.--Adjoins Vlacq on the S. It is a somewhat larger and a far more irregular formation. On every side except the E., where the border is unbroken, and descends with a gentle slope to the dark interior; ring- plains and smaller depressions encroach on its outline, perhaps the most remarkable being Hommel a on the N., which has an especially brilliant wall, that includes a conspicuous central mountain, a large crater, and other details. The best phase for observing Hommel and its surroundings is when the E. wall is just within the evening terminator.

Additional Information
Depth data from Kurt Fisher database
- Westfall, 2000: 5.05 km
- Cherrington, 1969: 2.8 km
- Satellite craters Hommel A, J and R are on the ALPO list of bright ray craters.
Nomenclature
- Named for Johann Hommel (1518 - 1562), a German astronomer and mathematician. In 1552 or 1553, Richard Cantzlar introduced transversal dot lines in graduations. It was a variant of the zigzag line system introduced by Hommel. Tycho Brahe obtained the zigzag line system from Hommel.
- According to Whitaker (p. 213), this name was introduced (in the form Homelius) by Riccioli; however the feature labeled with that name on Riccioli's map is what we now call Pitiscus. When, and by whom, the name Hommel became associated with the present feature is not entirely clear (from Whitaker's book). - Jim Mosher
