a unit of measurement of distance

Explanation: Light year is a unit of measurement of distance.

to how far light reaches in a year’s time

A light year refers to how far light reaches in a year’s time.

the distance that light can travel in an entire year, or 186,000 miles per second multiplied by 60 seconds per minute multiplied by 60 minutes per hour multiplied by 24 hours per day multiplied by 365 days per year equals 5,865,696,000,000 miles per year

A light year is the distance that light can travel in an entire year, or 186,000 miles per second multiplied by 60 seconds per minute multiplied by 60 minutes per hour multiplied by 24 hours per day multiplied by 365 days per year equals 5,865,696,000,000 miles per year.

the distance that light travels in a year so about 10 trillion kilometers

And a light year is the distance that light travels in a year so about 10 trillion kilometers, so say about 40 trillion kilometers tall.

6 trillion miles in distance

First, a 'light year' is 6 trillion miles in distance, so 'a billion light years away is a billion years ago…two billion lights years away is two billion years ago' is not even close to accurate but must be multiplied by 6 trillion to determine the number of years represented.

a unit of astronomical distance equivalent to the distance , that light travels in one yearroughly 6 trillion miles

A light-year is a unit of astronomical distance equivalent to the distance that light travels in one year, roughly 6 trillion miles.

the distance that light can travel in one year which is about six trillion miles

And a light year is the distance that light can travel in one year which is about six trillion miles.

as the unit of measurement – that is, the distance that light travels in one year

Scientists and astronomers therefore use the “light year” as the unit of measurement – that is, the distance that light travels in one year.

that light travels in the vacuum of space in one year

Aldebaran is about 65 light years away and a light year is the distance that light travels in the vacuum of space in one year.

5.88 trillion miles

A light-year is 5.88 trillion miles.

that light travels in one year at one year's speed of around 300,000 km/s, which is equal to 9,460 billion km away

A light year is the distance that light travels in one year at one year's speed of around 300,000 km/s, which is equal to 9,460 billion km away.
