20,000 years
Voyager 1 will pass by Proxima Centauri within 16,000 years, while it will take 20,000 years for Voyager 2 to reach it, and 18,00 years for Pioneer 11 to meet our neighboring star.
Would a trip to Alpha Centauri be possible in our lifetime?
Earth’s nearest exoplanet twin orbits a star about four light years from here. Now scientists say it’s possible to visit this system in our lifetimes by propelling a tiny spacecraft on the tip of a laser beam.
How long would it take to travel 40 light years?
Considering that speed, It would take aprox.: 59,627 years with today technology (https://www.google.com/#q=40+light+years+%2F+724000+km%2Fh&*). I read an article stating a spacecraft traveling 38000 miles an hour would take approximately 80,000 years to travel 1 light year.
What is the closest Sun to our Sun?
Proxima Centauri is a red dwarf Of the three stars in Alpha Centauri, scientists believe Proxima is closest to our sun, at 4.22 light-years away. Astronomers have discovered two planets for Proxima so far. It also has massive solar flares and might even be the source of a mysterious radio signal.
Where is Voyager II now?
The spacecraft is now in its extended mission of studying interstellar space; as of September 16, 2021, Voyager 2 has been operating for 44 years, 1 month and 15 days, reaching a distance of 127.75 AU (19.111 billion km; 11.875 billion mi) from Earth.
How long would it take to travel 4.2 light years?
Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations. Indeed, most of the humans involved would never see Earth or its exoplanet counterpart.

The results, which you can read all about in the journal Ast
How long to travel to Alpha Centauri?
Regular spacecraft would take more than 30,000 years to traverse the 4.37 light-years (25 trillion miles) to Alpha Centauri, but this nanocraft could complete the same journey in just 20 years, returning images and data to Earth of planets in the Alpha Centauri system.
Is the Alpha Centauri the second closest star to Earth?
2nd, 3rd and 4th – Proxima, Alpha Centauri A and B – Centaurus Proxima Centauriis the second closest star to Earth.
