A light year is a measure of distance, not time. Light travels 186,000 miles per second, so in one year light would travel almost 6 trillion miles -- that's a distance of one light year. Astronomers typically use light years as a form of measurement due to the huge distances involved. It's easier to say that a star is 4 light years away than it is to say 23 trillion miles.

First of all light year measures distance rather then time.
One light year is equal to the distance that light can travel in a straight line in 1 year. It is used to measure the distance between stars and similar.

A light year has nothing to do with time, human or otherwise.
A light year is a distance, and is the distance that light can travel in one year.

Um, I think everyone sort of missed it: since a light year is the distance that light can go in a year, a light year would be one year long, no?

A light year is a unit used to measure length, and so one light year is approximately 5,878,625,373,183.61 miles.

in human time one light year is the time measured in years for a human to die by a light emitting death cathode used by species 007889745433 when they visit Earth in the year 2115. cheers :D

In human time it's almost six trillion miles. But in dog years it's only about 840 billion miles. ;-)
