Cerebus Prime

Cerebus Prime is an inhabited planet located in or near Federation space, and is home to the Hiinkan species.

At some point in the 23rd century, a plague broke out among the local population. Starfleet responded to the crisis by sending a large medical team, which included Dr. Mark Piper, to the planet to see if they could find a cure. Eventually, Piper succeeded in curing the plague, and he was given a latinum honor medalion in recognition of his efforts. By 2265, the planet also contained three medical facilities that were named after Piper. (TOS novel: My Brother's Keeper).
