A irradiate year is a unit of length, simply as is one inch, a mile or a meter. However it is a very large unit. The is the street that light would travel in one year through a vacuum.

You are watching: How many miles is a light year

Light travels at precisely 299,792,458 meters per 2nd (about 186,282.397 miles every second), so:


1 irradiate year equals 9,460,730,472,600 kilometers.

1 light year equals 5,878,625,373,200 miles.

(The rate of light is exact but an earth year varies.)

For comparison:


~ earth is 0.000015812 irradiate years from the sun.

~ among the more quickly objects human being have ever sent into space, the Voyager I room probe, is presently leaving the solar mechanism at 17.1 kilometers every second. At that speed it would certainly take 17,532 years to travel one light year that distance.

~ The closest star to our sun is Proxima Centauri in ~ 4.2 irradiate years away.

~ our galaxy, the Milky Way, is roughly 100,000 light years in diameter.

How deserve to the speed of light be measured exactly?

In 1983, the meter was redefined in the worldwide System of systems as the distance traveled by light in 1⁄299,792,458 of a second. Together a result, the numerical value of the speed of light in meter per second is currently fixed exactly by the meaning of the meter.
