Barnard's Star is a red dwarf located 5.96 light-years away in the constellation Ophiuchus. It has the highest proper motion of any known star, moving across the sky faster than any other. Calculate your journey time with time dilation effects.
Barnard's Star is 5.96 light-years from Earth. That is about 56.4 trillion km (35 trillion miles), or 376,900 astronomical units.

Light from Barnard's Star takes 5.96 years to reach Earth, so the light you see tonight left Barnard's Star 5.96 years ago.
Voyager 1, the fastest object humans have sent into deep space, travels at about 17 km/s. It would need about 105,100 years to cover this distance.
Notable For: Fastest-moving star in Earth's sky, second-closest star system
At the speed of light, it would take 5.96 years to reach Barnard's Star. At 1g constant acceleration with deceleration, a traveler would experience about 4.5 years while approximately 8 years pass on Earth.
Barnard's Star has the highest proper motion of any star, moving 10.3 arcseconds per year across the sky. It's approaching our solar system at about 110 km/s and will be our closest neighbor in about 10,000 years.
Barnard's Star is 5.96 light-years from Earth, which is about 56.4 trillion km or 35 trillion miles. Light from Barnard's Star takes 5.96 years to reach us.
Barnard's Star is 5.96 light-years from Earth. One light-year is about 9.46 trillion km, the distance light travels in one year. In parsecs, Barnard's Star is about 1.83 parsecs away.
This time dilation calculator lets you enter a distance in light-years and acceleration in m/s² to see how time dilation affects your journey. It shows differences between traveler and observer times, maximum velocity, energy requirements, Doppler shift, Lorentz factor, and how distances vary between reference frames. Charts appear after you calculate.
Time dilation is an effect from Einstein's theory of special relativity. The faster you move, the slower time passes for you compared to someone standing still. At 90% of light speed, time passes about 2.3 times slower for the traveler than for someone on Earth.
The Time Dilation Formula is:
Where:
t' = time measured by the observer (on Earth)
t = time experienced by the traveler
v = velocity of the traveler
c = speed of light (299,792,458 meters per second)
