systems with lantern years?

Answers:
because the objects surrounded by the solar system are close and the objects outside are so much farther away.
The nearest star to our solar system is 285,0000 AU's away
How far is it from your home to your school contained by inches? Isn't that a silly way to weigh up such a large distance? All extra solar distances are vastly larger than what we accord with here on puny dust.
Because it's much simpler to use that part of measure a bit than using miles...after a while..there would be route too many zero's involved..because of such yawning distances involved.
You other use a unit of means appropriate to the task. Why do you standard yourself in inches but the distance to the subsequent state in miles? Some entry are so vastly different that they are hard to comprehend contained by another unit of manoeuvre.
1 A.U. is the distance from the earth to the sun so its handy for empathy relative distances of the planets. But you could also talk in the region of those distances in Light Minutes. Although I don't hear it used normally, The distance from here to the sun is 8 light minutes. Do you really want to multiply out how few light years to be exact? .00001547 Light Years or something like that.
It is mainly because astronomers are inefficient and get writers' cramp. It is easier to write Jupiter's distance from the Sun is 5.2 AU than 484,000,000 miles, a short time ago as it is easier to say Alpha Centauri is 4.3 lightyears away (or 1.3 parsecs) than it is to write 900,000 AU or 26,000,000,000,000 miles. And doing calculation with a 2 digit number are easier also.

For indistinguishable reason we use foot and inches (or centimeters and meters) to measure things contained by our homes and miles (or kilometers) to measure distances to other cities.
If we used AU for distances to other stars, we would appendage up with huge numbers to treaty with.
Proxima Centauri is 4.22 pale years away, which is 266,877 light years.
And if we used buoyant years inside our solar system, we would be dealing with really tiny numbers.
The Earth is one AU from the sun, which is .0000158 night light years.
Its easiest if conveniently-sized units of weigh are used.
Because the AU is too small to measure distances outside the solar system. It would be close to measuring down your house in nanometres.
Scale. Why do we measure rooms surrounded by feet and distances between cities contained by miles.
Same reason.
AU / Astronomical Units are equal to roughly the distance of the Earth from the Sun (about 93 million miles).
Light years are much handier for stellar distances.
For example,
The Earth is 8 pallid minutes from the Sun, if we rounded everything to "light hours" let say, that's in the region of 670,651,200 miles per hour.
Earth is 0.12 light hours from the Sun, (about).
Mars is more or less 0.3 light hours from the Sun
Jupiter is give or take a few 1.2 light hours from the Sun
Pluto is give or take a few 8 light hours from the Sun
Proxima Centauri is almost 4.3 light years from the Sun or
37668 wishy-washy hours from us.
given that 4.3 * 365 * 24 = 37668
light years * days * hours = # of hours
So if we want to know how several AU's to Proxima Centauri we just multiply how several AU's in a reading light hour
1 / 0.12 ~= 8.3 = for simplicity lets voice 8
so that 37668 * 8.3 = 312644 AU's from the Sun to Proxima.
if we used astro units to judge how far away other solar systems are that would be a massive # even though astro units are surrounded by millions on miles long lightyears i think it said 1 million astros unit in a pallid year so thats one big #
