Answer 1

Since my computer is busy (answering questions), I had to do what I could on this one with only

my little pocket calculator.

I found a way to do it and keep all the significant figures, but I decided it didn't matter, because:

-- In miles, it's going to be 7.671 x 1033 (rounded)

-- In light-years, it's 1.305 x 1021 (rounded). I recognize that as almost exactly

1 hundred-billion times the size of the observable universe.

-- Whatever answer I give, I'm confident that the questioner is never going to

come back and challenge it.
