Well, if we're getting
technical, it is the distance that light travels in a vacuum in one
Julian year (365.25 days [86,400 SI seconds per day]).
Oops, looks like I nitpicked the wrong person. I've been demoted to an up-arrow.
Since it is effectively a measure of Time as well as space, and since time and motion are directly related to the Planck Length, How far would it be in relative Planck Lengths?

I wood guess about 10 to the Zillionth power.

A light year is not in any way a measure of time. Neither is the Planck length. Both are simple units of length.
A light year is 9.4542549555 x 10
15 m. A Planck length is 1.61619926 × 10
-35 m. So a light year is approximately 5.85 x 10
50 Planck lengths. (Not sure what a "relative" Planck length is.)

You're off by a zillion minus 50.

I guess I'm just a Bad guesser. There's nothing much i can do about that, i guess.
I don't have much experience with working with Planck planks. They're just toooo small to hold in place whilst you try to nail them down.

You're probably using the wrong tools. Since I started using Planck nails and a Planck hammer, I've had no problems at all.
Right now I'm training Maxwell's Demon to do the work for me, so I expect things will get even easier in the future.

Is that close enough for engineering purposes?

That's the first thing I saw as well, but I saw the entire bat, with wings, hind legs and complete with the claw/fingernail(s) on the upper edge of the wings. A rather chubby bat tho, he needs to work out more.
If this were the first image seen of this nebula, I'm sure it would have been named the Bat Nebula because it's just so obvious.
