How long would it take humans to travel one lightyear?

Even if we boarded the space shuttle Discovery, which can travel 5 miles per second, it would take us about 37 or 200 years to travel a light year. One of the most distant exoplanets we know of in the Milky Way is Kepler-443b.

One of the most distant exoplanets we know of in the Milky Way is Kepler-443b. Traveling at the speed of light, it would take 3000 years to get there. Or 28 billion years, going at 60 miles per hour.
