The Veil Nebula. What’s a few trillion miles between friends?

I believe someone’s math is incorrect in this article. I’m not spoiling the fun, just correcting the record. The image is truly breathtaking and wondrous! But Numeracy counts. :~)

63,000 just didn’t seem big enough, and I was right. Somebody’s calculation re: the width of the Veil Nebula is off by a factor of 100.

Given:
A light year is approx 6 trillion miles, or 6,000,000,000,000 miles.

At a width of 110 light years, the Veil Nebula is therefore about 660,000,000,000,000 miles across.

The sun is about 93 million miles away, or 93,000,000.
If you do the math (660 trillion / 93 million), 110 light years across is not about 63,000 times the distance between earth and the sun as claimed in the article, but instead is about 7,000,000 (7 million) times! An even more incomprehensible number than 63,000, I know.

But, what’s a few trillion miles between friends?
