Minus 5 points for writing "Distance From Earth: 1,999 light-years" and not "Space: 1999"...
Current journey time to Kepler-589 b: 53.7m years
Journey time to AU Mic c: 859,000y
Practically a day-trip!
AU Microscopii c is so local, the next advanced civilization along probably doesn't realize we're not in the same system... :-) We could probably get there while we still had ten fingers and only two eyes... 🙂
Current journey time to Kepler-555 b: 85.2m years.
#StarTrek journey time (at Warp 9): 2.1 years.

None of these casual calculations account for the expansion of the #universe, or probably many other factors which your not-actually-any-kind-of-astrophysicist host is blissfully ignorant of.
So bear in mind that they are probably overly optimistic.
Cryosleep well, my dear exonauts... ;-)

Current journey time to Kepler-1179 b: 36.3m years.
If we could divert the Voyager 1 probe to rendezvous, the arrival time shortens to a cool 23.9m years. But that's with no human¹ crew, of course.
(¹ "Earthling", rather. The spacefarers of 24mAD would be no more "human" than a cuttlefish. 🙂 )
Current journey time: 95.2m years.
Race ya!
Current journey time: 68.6m years.
Current journey time: 30.7m years.
And none of this even factors in relativity, of course.
In a nutshell; these journeys require a commitment much longer than current recorded human history, and the sustained corporate will to achieve them over an evolutionarily significant number of generations; this from a species who likes to change government every 4 years or so. And who are we to dictate mission parameters to our distant descendants anyway?
Obviously, the possibility exists to go faster than 25000mph; the fastest speed reached by an UNMANNED craft is about 150,000mph; but it was falling into the sun at the time...
Nevertheless, it's realistic to think we could accelerate humans to much greater speeds. The problem is, those journey times stay boggling. Even at the theoretical max of light speed, we'd STILL have problems getting to even the most local stars, before we'd forgotten why we left in the first place.
The #exoplanets thing is just a bit of fun (for me at least) keeping a focus on how absurdly unattainable these things actually are.
The times are calculated (VERY roughly!) thus:
Assume we could re-attain and sustain the fastest speed a human has ever travelled =~ 25000mph = 219m mpy.
1 light year = 5.87x10^12 miles.
Divide latter figure by former to get journey time for 1LY = 26843y.
Multiply by distance to target in LY.

@kevinmgill not even the total perspective vortex, and even this is too much for my brain #hhgttg #SpaceIsBig
