Terra 10



Terra 10 is an early Human colony, presumably settled during the 22nd century. By the 23rd century, the colony had been shrunken due to exposure to natural radiation present in the region of space where the colony was settled.

When the planet started dying, the colonists desperately sought the help of the USS Enterprise (NCC-1701), shrinking the crew of that ship in the process. Luckily, the Enterprise was able to restore its own crew to full size, rescue the colony, and relocate it to a distant Class M planet. (TAS Episode: The Terratin Incident)
