So best case about 28,000 years.

Which is a bugger as I'm out that week.

I think there is a theory that we can travel nearly the speed of light , but yeah even then we are a millennia away :(

If you could accelerate at 1g, you could reach it in 7 years, in your reference frame.

Wait for the observer... isnt it.... 1800 / 17.... 100 years.

So that means, a baby could reach the exoplanet, before it dies of old age, on a spaceship travelling 99% the speed of light, which can theoretically built right now.

How did you arrive at your calculation of 7 years?

Thanks!

I eyeballed it from here[1], which I should have just linked with my post.
