Note that they were used in four separate episode as four different planets in TOS, as Vulcan in
Voyage Home and the AOS movies, once as another planet in TNG, twice as different planets in
Voyager and once as yet another planet in Enterprise.
Most recently they were featured as themselves (for once) in Picard.
The best use honestly was in Bill and Ted’s Bogus Journey when their robot doubles decided to drive up to Vasquez Rocks and throw them off that cliff, all because they had been watching Star Trek.
