It's a measure of distance, the amount of distance light travels in a year. approximately 5.87 x 10E12 miles.

A light year is the number of miles that light can travel in one of our earth years which turns out to be around:

5,865,696,000,000

(the non-maths version of what Loosehead said).

Trev
To quantify this a little more. The sun is at a distnace of 8 light minutes. The nearest star to earth is 4.3 light years away.
A light year is a hell of a long way. 5.866 billion miles (UK), or 5.866 trillion miles (US).

I would do some research on the internet first before asking the question - or has this function of the internet been totally lost on our schoolchildren?



Dark years last for ages (Dark Ages. Getit? Hahahaha!)
