31 light-years away. Proxima Centauri b is about 4. Don't think I'd like to visit either.

I'd like to visit Kepler-452b but it's 1,500 light-years away: https://en.wikipedia.org/wiki/Kepler-452b

Kepler-452b has 2X Earth gravity.
But seriously, these are all too far away for us to reach in any of our lifetimes, barring some insane discovery that breaks all the rules as we know them.
(What's a mere six orders of magnitude when it comes to physical engineering, anyways? Just spin up a few more jobs on the borg clusters, and if that doesn't work, Moore's law will rescue you in a decade or two...)
