I'd be far more freaked out if they discovered not only a planet there, but with characteristics that resembled Vulcan. Fiction can get some things close to correct sometimes, but that would be disturbingly too close.

Damn this is the second time they killed Vulcan?

I mean, I never cared if it was exactly located in any specific spot. Call me when they prove nothing like it could exist anywhere.

We haven't had a eugenics war so we're clearly not in the right timeline, so it would make sense Vulcan would be somewhere else.
