Let That Be Your Last Battlefield - S3-E15
Corrected entry: Kirk says Cheron is in an uncharted region of the galaxy. How does Kirk know about it then? Later Spock identifies its exact position when he says the ship is heading for it. Again, if it's "uncharted" how do they know where it is to figure out this stuff.
Correction: Cheron may be an obvious 'marker', a known distant system that has yet to be charted in detail, but the existence and location of Cheron itself is known, much like knowing the moon was above earth centuries ago, but its details had yet to be charted.
