When talking about the distances that separate stars and galaxies. A light years is the distance that light travels in one year.
A light year.
A light year is the distance that light travels in a year, so it is a measure of distance, not time. Light travels at about 186,000 miles per second or about 300,000 kilometres per second. There are 31,536,000 seconds in a year. There is about 5,869,713,600,000 miles in a light year or about 9,445,950,434,500 kilometres.
A light year is the distance that light travels in a year. We use it because it allows us to measure huge distances.
light-year(:
i also heard about the light year never listened about light minute
We're just one light year from home, now.
You don't use it, it is a unit of measurement.

We are a light-year away from our destination.The newly discovered, earth-like planet is a light-year away from us.
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.
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.
The light year was not discovered. It was made up, by people who kept coming up with distances like [ 25,866,280,000,000 miles ] in their work, and soon realized that they were going to need something bigger than a mile, so they invented the light-year.
