Geological Chronicle
Paracelsus is an impact crater measuring 85.88 kilometers in diameter on the Moon's far side. It is located east of the crater Barbier and southwest of the large walled plain Vertregt, with Mare Ingenii situated to the south. The crater is named for the Swiss-German doctor and chemist Philippus Aureolus Theophrastus Bombast von Hohenheim, known as Paracelsus.
The crater dates to the Imbrian period on the lunar geologic timescale. It is circular in shape, with an eroded yet moderately well-defined rim that shows little terrace structure along the inner wall, where features are radial to the center in places. The smaller crater Paracelsus Y intrudes into its northwestern rim, and Paracelsus P is attached to the southwest exterior.
The interior floor is level and contains a central peak offset slightly west of the midpoint. A few tiny craterlets mark the southern half of the floor.
