Yes, long before Star Trek. Before Einstein, in fact.
Vulcan as a planet inside Mercury was hypothesized to explain a perturbation
of Mercury's orbit that could not be explained by the known planets. But
Einstein's theory of relativity explained Mercury's motion, and analysis
of Mercury's motion now shows there are _not_ any planets inside its orbit.
