quantumclaustrophobe say: At current speeds, many hundreds of thousands of years... As an example - our fastest probe right now is Voyager 1; it's about 13 light *hours* away from Earth - about 1/700th of a light year - and, it was launched 40 years ago.

Athena say: 39 years, earth time, if you traveled near the speed of light.
Less time on the ship of course.
Much longer if you took a train.

poornakumar b say: If your spaceship travels at a speed of a 'n ͭ ͪ of speed of Light', it takes n times 39 Light years to reach there.
A maximum speed of a two thousandth of Light speed is bandied about (I don't believe),
c/n = c/2000 ͭ ͪ and that means
2000 x 39 = 78000 years
for a one-way trip.
But I feel (where is the engine ?) it can be in the range of a few hundred thousand years.
Also dynamics in Space (engine if any & its speed) are yet to be sorted out & an engine invented.

Iridflare say: "Habitual" should be "habitable", and we don't know that they are! They're at distances from their sun which mean the temperature ranges will allow liquid water, but that doesn't tell us what the radiation environment is like - red dwarfs aren't good candidates for life supporting stars.
-
Nyx say: At least 39 years at lightspeed. Longer, if if you're traveling slower.
-
Newdivide1701 say: Needless to say to reach such distances within a reasonable amount of time is the warp drive, and that drive system is still on the drawing board.
But once completed and approved for manned interstellar flights, the claim is that the drive can achieve 100 times light speed, and with that it would take that drive about 4-1/2 months for the ship to reach that star system.

Bill say: One of our fastest space craft is Voyager. Voyager 1 is travelling at 17,043 m/s (55,920 ft/s) relative to the Sun (about 3.595 AU per year). It would need about 17,565 years at this speed to travel a complete light-year. To compare, Proxima Centauri, the closest star to the Sun, is about 4.2 light-years. It will take 73,773 yeas to get to P.C.
To go 39 light years just multiply 39 times 17, 565 Years = 298,705 YEARS

Alpha Beta say: It depends on how fast you can move the ship ... at light speed (which would be impossible), it would take 39 years. At current speeds like the shuttle or other spacecraft, it will take thousands and thousands of years.
