Lightyear is a measure of distance. If I remember correctly it's about 6 trillion miles.

Glad you posted this...I've been looking for an out of the way place for a vacation. ha.

5.88 trillion miles

97,761,600,000 or so miles. 186,000 miles a second x 60 x 60 x 24 x 365 is my guess.

It's like a light sabre but longer... ;-)

The distance light travels in one year, approx. 6 trillion miles. The very notion of a light year would've shocked the ancients, and even most people right up until a couple of centuries ago, who thought light was instantaneous; i.e., travelled infinitely fast. But compared to the size of the Universe, it crawls (at least for outside observers).

I don't know how long a light year is, but the Millenium Falcon made the kessle run in under 5 parsecs. ;^)

Is that a trick question? It's a year. Or the distance light travels in a year.

Light travels at a speed of 186,000 miles per second.
31,536,000 seconds in a year.

5,865,969,000,000 miles.

A light year is the time/distance it takes light to travel during one earth year. Unfortunately, I'm not mathematically astute enough to tell you how to calculate the distance light travels in one earth year.

1 year.
