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.

Not really. A light year is a measure of distance. It is the distance light can travel in one earth year, about 6 trillion miles
False the light year is not a unit of time it is a unit of distance true.
Distance (metres) = velocity (metres / sec) * time (seconds) > velocity of light = 299 792 458 metres per second 1 year = 365.2425 days = 31 556 952 seconds > Distance = 9 460 536 207 068 020 metres Distance = 9.46054 * 1015 metres approx.
The measurement of light is in lumins. Pronounced ( loo-mins)
Usually such distances are measured either in light-years, or in parsecs.
Distance
how far u can travel at the speed of light in a year
No. A light year is a measure of distance. It is the distance light travels in a year.

Distance
Because that's how it is defined. A light-year is the distance that light travels in a year.
it is time
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
"Light year" is a unit of length or distance, equivalent to roughly 5,878,600,000,000 miles. (rounded)
A light year
because the stars are very far away so the astronomers use light years
False the light year is not a unit of time it is a unit of distance true.
