A light year is the distance that light travels in a vacuum in one year. An AU is the measure within the solar system equal to the mean distance from Earth to Sun.

So you're asking what the difference is in miles? That's rather complex for calculators or anything. (186000 times 31536000) minus astronomical unit distance.
Scientific Notation:
(5.865696 * 10^12) - AU
About 5.86 trillion miles minus the distance of an AU.
I think around 5865603000000 miles, or 5.865603 trillion. Not very big in proportion.

"A light year is the distance that light travels in a vacuum in one year. An AU is the measure within the solar system equal to the mean distance from Earth to Sun."
Does the answer look familiar? It's what you wrote and is exactly correct :)

An AU is the distance between the Sun And the Earth...about 94 million miles. A ly is the distance light travels in a year...about 6 trillion miles

Whats An Astronomical Unit

A.U. (Astronomical-Unit) is the distance = to the 2 farthest points on earth. (e.g.) N-Pole & S-Pole. it's = to 14,346 KM. L.Year is the distance light travels in 1 year. this is ) to 6 TRILLION + miles. parsec is the distance light has traveled in the time since the BB. if you take 10^3 ( 1K or 1 thousand) then take that and ^3, and keep following the same pattern for 17×, you'll get the appx amount a parsec is in light-seconds.

You've got the definitions. So an AU is about 8.5 light minutes. Put another way, a light year is about 6 trillion miles, an AU only 93 million. So a lightyear is almost 700,000 AU.

You uhhh answered your own question. A light year is a lot bigger then an AU. For comparison, light takes just 8 minutes to travel to earth from the sun (and thus travel one AU).

Another viewpoint is that 1 AU is 500 light seconds, i.e., the distance that light travels in 500 seconds. This is contrasted with a light year, wherein light travels for 31.6 million seconds, or 63,000 times longer, or farther, however, you want to look at it.

You seem to have the answer....though an AU CAN CHANGE....depending on where the Earth is atm. I believe, not sure, but at close range a AU is about 7 mins and at furthist distance, about 7.5 mins....totally not sure on that and only thing I'm trying to point out here is an AU can change.

One light year = 6 trillion miles & one AU = 93 million miles so one light year = 64516.129 AU
