Correction to previous post:

1 light year is approximately 6 trillion miles, so 5 light years is approximately 30 trillion miles.

Hence the sentence

Now, aside from our Sun, the next nearest star to us, Proxima Centauri, is about 5 light years away (roughly 6 trillion miles).

should read

Now, aside from our Sun, the next nearest star to us, Proxima Centauri, is about 5 light years away (roughly 30 trillion miles).

And for anyone who's actually reading this stuff, I used 30 trillion in my calculations, not 6 trillion; the '6 trillion' was a writing error only.
