A light-year (or light year, abbreviation: ly) is a unit of length used informally to express astronomical distances. It is well over 9 trillion kilometres (or about 6 trillion miles). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year. Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.
The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist and popular science publications. The unit usually used in professional astrometry is the parsec (symbol: pc, approximately 3.26 light-years; the distance at which one astronomical unit subtends an angle of one second of arc).
As defined by the IAU, the light-year is the product of the Julian year (365.25 days as opposed to the 365.2425-day Gregorian year) and the speed of light (7008299792458000000♠299792458 m/s). Both these values are included in the IAU (1976) System of Astronomical Constants, used since 1984. From this the following conversions can be derived. The internationally recognized abbreviation for light-year is "l.y.").

So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine the distance of objects several billion light years away from Earth. Lesson by Yuan-Sen Ting, animation by TED-Ed.

I go back on what I said,
I take back the things I did.
I know, I've been unfair to you.
Oh, I know, I've been unfair to you.
It's like, I'm a staple in the middle of the page,
Where the ink won't run, and the ink won't stay.
I know, I've been unfair to you
Oh, I know I'm never there for you.
You and me are light years apart,
You and me are light years,
You and me are light years apart,
You and me are light years.
It's not up to me, oh
It's down to you.
I can change if you can too.
We got caught in the middle,
Caught out here,
We got caught in the middle,
With every word, every time.
Our lives break up and we never compromise,
These words break down cause we never took the time.
You and me are light years apart,
You and me are light years,
You and me are light years apart,
You and me are light years.
It's not up to me, oh
It's down to you.
I can change if you can too.
We got caught in the middle,
Caught out here,
We got caught in the middle,
With every word, every time.
I go back on what I said,
I take back the things I did.
I know, I'm never there for you.
Oh, I know, I'm never there for you.
You and me are light years apart,
You and me are light years,
You and me are light years apart,
You and me are light years.
It's not up to me, oh
It's down to you.
I can change if you can too.
We got caught in the middle,
Caught out here,
We got caught in the middle,
With every word...
It's not up to me, oh
It's down to you.
I can change if you can too.
We got caught in the middle,
Caught out here,
We got caught in the middle,
With every word, every time.
You and me are light years,
You and me are light years apart,
You and me are light years.
You and me are light years,
You and me are light years apart,
