A light year isn't a year. Its a distance.
A light year is the distance light travels in one Earth year (about 9 trillion kilometers or 6 trillion miles).
I'll bet if you googled "light year" you would have found it in a few seconds.

A light year is a measurement of distance, not time as one might believe. The speed that light travels in open space is 186,282.397 miles per second. Now to figure out what a light year would be, you would multiply the number of seconds in a whole year by 186,282.397 and that equals one light year.

A light year is the distance light can travel in one Earth year (..365 days..)

A light year is a measure of distance, not a measure of time.
It is the distance that light travels in 1 year.

Light Year is a distance in miles or kilometers or whateevr way you want to calculate distance. It is not an actual year. It refers to the distance light travels in one year.

For a start, a light year year is used as mesurment for distance, not time.

a light year is a measure of distance not time .. it equates to how far light travels in one year

It's not. That's like asking how many gallons in a mile.
A light year is a unit of DISTANCE, not time.

No science geek would be unaware of facts like that. Get yourself together and pay attention in class.
