Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

I had to check that math in my head.
4ly = 4yr • 3.1 * 10^7 sec/yr • 3 * 10^5 km/sec ≈ 36 trillion km
Multiply by 0.6214 to get miles = 22 trillion miles
I’m sure they have the right number. Mine was a ballpark estimate, as one does in physics. I think Proxima Centauri is about 4.2ly from Earth.
"But the closest star is Sol"
I was just doing the extra conversion because the comic is in miles. The figures are pretty close, and the extra .2ly would account for the discrepancy. Looks good to me!
Yes, too much rounding will do that (also the approximation of a year shaved off more than a percent). Taking more precise numbers, it fits:
4.2465 ly * 365.2425 days/yr * 24 * 3,600 * 299,792,458 km/s * 0.6214 ~ 24.96 e15 miles
