How Long Would It Take Humans to Travel One Lightyear?

If we were to board the space shuttle Discovery, which can reach a speed of 5 miles per second, it would take us approximately 37 or 200 years to traverse one light year. The most distant exoplanet that we know of in the Milky Way is Kepler-443b. If we were to travel at the speed of light, it would take us 3000 years to reach it. Alternatively, if we were to travel at a speed of 60 miles per hour, it would take us 28 billion years.
