Rimillia

Rimilia, home to the Dumadan, was a planet locked tidally with its star until 2267, when the USS Enterprise, in a project led by then-Lieutenant Commander Montgomery Scott, managed to grant it a normal rotation through the application of multiple ion thrusters placed around its equator. (TOS novel: Twilight's End)

While helping on a project to terraform Venus, Captain David Gold reminisced on this event with Captain Scott, citing it as justification for the alteration of the inner planet.
