Frequently Asked Questions
How long to travel to Gliese 667 C?
At light speed, it would take 23.6 years to reach Gliese 667 C. At 1g constant acceleration with deceleration, a traveler would experience about 11.7 years.
What would the sky look like from Gliese 667 C's planets?
From a planet orbiting Gliese 667 C, you would see two other suns in the sky - the companion stars Gliese 667 A and B, which would appear as very bright stars.
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.

What is Time Dilation?
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.
What is the Time Dilation Formula?
The Time Dilation Formula is:
t' = t / √(1 - v²/c²)
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)
