"Light year" is a distance. It's defined as the distance light travels in one year,
through vacuum.
That's a huge distance compared to the daily experience of human beings ... about
5,874,600,000,000,000 miles, or more than 31 thousand round trips to the sun and back.
It's used in discussion of the distances between objects in space, and it actually
turns out to be not a so large a unit at all. The nearest star outside of our solar
system is about 4.2 light years distant from us, and the nearest galaxy outside of
our Milky Way is about 2.5 million light years distant from us.

∙ 15y agoA light year is a measurement of distance. It is the distance light travels in the vacuum of free space in one year. The speed of light is 186,282 miles per second. There are 31,536,000 seconds in a year.
31,536,000 x 186,282 = 5,874,589,152,000
One light year = 5,874,589,152,000 miles. That's 5 trillion, 874 billion, 589 million, 152 thousand miles.

∙ 9y agoA light-year is a unit of length equal to the distance that light travels through vacuum
in a year (about 5,787,499,810,000 miles). It is often confused as a unit of time.
The official definition of a light year uses the Julian year of 365.25 days and the speed of light 2.99792458 times 10 to the power 8 metres/sec, so a light year is 9.460730473 times 10 to the power 15 metres or 5,878,625,373,180 miles.

Why is a light year a unit of distance rather than time?
A light year is a distance measurement because it would take something a year travelling at the speed of light to cross. It is called a light year because it helps astrologers/scientists understand the vastness of the distance between two things; for example, Our Galaxy (The Milky Way Galaxy) and our nearest Galaxy (Andromeda Galaxy)

How long is a light year what does a light year describe?
A light-year is the distance light can travel in one year. Light travels at 186,000 miles per second. Multiply that by 3600 seconds in an hour and then by 24 hours in a day and 365 days in a year and you will get the distance in one light-year.A light year is defined as 9,460,730,472,580,800 meters exactly, derivedfrom the distance that light travels in vacuum in one Julian year.

It depends on the circumstances. My four, nearly five, year old understood the concept, but this was where a parent was involved.

I also know that at three years a child will definitely not understand as the chances are they still don't understand death as meaning someone is gone.
