Sahndara

From Memory Alpha, the free Star Trek reference.

Sahndara was the original star whose system was home of the race that would become the Platonians. Before Sahndara exploded around 400 BC, a group of thirty-eight refugees traveled to Earth where they settled during the time of Plato.

After the time of Plato passed, the settlers moved on to another planet, a class M planet, which they named Platonius. Here they continued to follow the teachings of Plato, but soon they discovered that they had developed psychokinetic powers, attributed to the planets kironide-rich food. (TOS: "Plato's Stepchildren")
