The light-year is the distance light travels in a year. Since this sometimes causes confusion, please note that a light-year is a unit of distance; NOT a unit of time. A light-year is approximately 9.5 x 1012 kilometers. (A light-year is defined to be exactly 9,460,730,472,580,800 metres.)

What is the proper definition of a light year?
The distance traversed by light in one mean solar year (about 5.88 trillion miles)
What is the term for the distance light can travel in one year in a vacuum?
The distance light travels in one year is called a light year.It is approximately 6 trillion miles.9.4605284 x 1015 metresLight year is the distance traveled by light in one year. we just cannot imagine this. Because light travels 3*108 m/s. so just think how much it will travel in one minute, one day, one week, one month & one year.Exactly 9,460,730,472,580.8 (just under 9.46*1012) kilometers.
