The light-year, alternatively spelled lightyear, is a unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometres (9.46×1012 km) or 5.88 trillion miles (5.88×1012 mi). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days).[1]https://www.iau.org/public/themes/measuring/ Because it includes the word “year”, the term light-year is sometimes misinterpreted as a unit of time.[2]https://en.wikipedia.org/wiki/Light-year

So how long it would take us to travel a light-year? If we were a space shuttle that can travel five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 13,578,000 days, or 37,200 years to travel one light-year.[3]https://futurism.com/how-long-would-it-take-to-walk-a-light-year. What about walking? That would take us some 225 million years (that’s assuming that you managed a constant speed of 20 minutes for every mile and didn’t stop for any bathroom breaks…it would be a little trying, to say the least, especially when one considers that modern humans have only been around for about 200,000 years.
