A light year is a unit of length: the distance light travels in one year, equal to about 9.461 x 1015 meters. It's used in astronomy to describe objects that are far enough away to be counted in light years, which is basically most things outside our immediate solar system.

What is a light year used for?
A light year is a measure of distance and is the distance light travels in one year's time. The light year is used to describe the enormous distances between various objects in space. In one year, light travels about 6 trillion miles.
What is a light-year and when is used most conveniently?
Its the distance light travels in a year, and its used to measure stellar distances.
What is a measurement of distance based on the speed of light?
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.
How light year is measured?
A light year is a unit of length used in Astronomy to define distance. One light year is equal to just under 6 trillion miles.
Why a light year used in astronomy?
Because of the vast distances in space and a light year is the distance of light travelling at 186,000 miiles per second in one year.
What time period is light year used?
A light year is NOT a period of time. It is a distance of about 5.86 trillion miles.
What is a light year and why do scientist use it?
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
When is a parsec used?
Parsecs are used as units of measurement for the enormous distances in space. One parsec is roughly 3.3 times greater in distance than one light year. A light year is the distance light travels in one year in a vacuum.
What is the distance used to calculate light-years?
Light-year is the distance in this case. It is the distance light travels in a year, and is equal to about 9.5 x 1012 kilometers.
Which unit of measurement uses the distance light travels in one year 9470000000000?
The distance light travels in one year is called a light-year. To get the number 9,470,000,000,000, the unit used is the kilometer.
A unit of length used to measure how far light travels in one year is called?
A "Light Year".Roughly 5,878,700,000,000 miles .
What can you use light years for?
Light years are used to measure the great distances of space. One light year is about 5.86 trillion miles. This is the distance light travels in one year's time.
