Can we get to Proxima Centauri B?
It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!
Why Proxima Centauri B is habitable?
Is Proxima Cen b habitable? Proxima b is a 1.3 Earth mass planet orbiting its star at about 1/20th of the Sun-Earth distance, which places it well within the so-called Habitable (Goldilocks) Zone. It receives an amount of energy from its central star that is about 2/3 of that received by the Earth from the Sun.
How far is Proxima Centauri B from Proxima Centauri?
4.24 light years

Will humans ever reach another star?
But, even with all that power, we are still nowhere near reaching the stars. To reach the stars in a shorter time we’ll need a way of travelling at a decent fraction of the speed of light — somewhere between a tenth and a fifth. At that speed a hypothetical probe could get to the closest stars in forty to eighty years.
How quickly could we get to Proxima Centauri?
about 54,400 years
New Horizons was traveling at speeds that topped 52,000 mph, but even at that rate, it would take about 54,400 years to reach Proxima Centauri. There are indeed faster probes out there.
How fast would we get to Proxima Centauri?
That trip itself took nine and a half years. New Horizons was traveling at speeds that topped 52,000 mph, but even at that rate, it would take about 54,400 years to reach Proxima Centauri.
Could there be a star closer than Proxima Centauri?
Proxima Centauri is a dim red dwarf that is around 4.2 light years from Earth, and it was discovered in 1915. This means that the discovery of a star closer to us than Proxima Centauri is extremely unlikely, however what is more likely is the discovery of a closer brown dwarf.
