It's kinda a dumb question but I was wondering
-
A light year (ly) is the distance light travels in one year. The total number of miles in a light year is 5,865,696,000,000 miles.
Just a little fun fact here--- Light travels at 186,300 miles per second. If you started at the Sun and traveled at the speed of light for one year, you would still only be a quarter of the way to the closest star to the Sun, Proxima Centauri, which is about 4.2 light years away. Talk about a long vacation!

Don't get confused and think 'year' so it must be a measurement of time. It is the distance that light, c, can travel in one year. It is approximately 9.4605284 × 10^15 metres. Very long indeed. It's used on the astronomical scale because it is impractical to use even distances like miles or kilometres. Lightyears are a very basic astronomical measurement. Parsecs are a little longer and a little harder to understand, but look them up if you're interested.

The distance light travels in one year at 186,000 miles and change per second during a 365.25 day year.
Roughly 5.8 trillion miles.

It is the distance that light travels in one year assuming outer space (vacuum) conditions.
-
The distance light travels in one year.
Light travels at 278,000,000 miles per hour. So, send a beam of light out into space and where it ends up in one year's time will be one light year!
