Why Doesn't Earth Orbit alpha Centauri?

[FatAndFaithless]

Yeah Alpha Centauri is ~4.37 ly, the sun is only ~93 million miles.

My understanding is light travels 6 million miles a year. So we are about 15.5 light years from El Sol. It is also my understanding that 15 is more than 4.37. while 4.37 X 6 is less than 93.

Ehh, no.  A light year is (roughly) 6 trillion miles.  We're nowhere near a lightyear away from the sun.  It only takes light ~8ish minutes to travel from the sun to the earth, which is ~.000016 light years.


~4.37 ly to Alpha Centauri, ~.000016 ly to the sun. We're vastly, vastly closer to the sun.
