A light-year is a unit of distance, not time. It's the distance light travels in one year.

One. The Earth year measures time. The Light Year measures the distance light travels in a time period of one year. Therefore, both are measuring the same length of time: one.

Well a earth year and light year don't measure the same thing. A earth year measures time well a light year measures distance. On light year it the distance light can travel in a year.

A light year is a measurement of distance. An earth year is a measurement of time. You cannot compare the two. A light year is the distance light would travel in one earth year.
REALLY IT'S CONFUSING AT FIRST BUT GOING ON IN PHYSICS IT BECOMES EASIER........

Light Year is a distance unit. Simple earth year is a unit of time. So there is no match between them

They are not comparable, because a year is a measure of time and a light year is a measure of distance. One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles).

What Michael B said. It's a measure of distance. And, it's very, very, very far away. It would take a loooooong time for astronauts to reach stars, which are many light years away.
Btw I don't blame you for getting confused. The name IS confusing, isn't it?

One...a light year is a distance, not a time. A light year is simply the distance that light will travel in one year...Although time is relative to speed (as you approach the speed of light)...light travels at the same speed regardless of the speed of the observer. That being said...light will always travel a given distance in a given length of time, regardless of the frame of reference...

simple dude..multiply,186,000 mph into 24 hrs into 365 days and the result u get is the answer to your question.
