Hi, just noodling around.
Websters gives it as 1pc = 3.27ly
It's the distance an ange of one minute subtends at a distance of one au.
Don't be afraid of a little trig. au means astronomical unit. Lookit up.
Would you like to know how to derive a parsec conversion number for yourself?
I have only scanned the local space discussion, but lots of
cool facts there. Get this: At JPL we are designing an
interferometric telescope system that will image Earth-like
planets within 50ly. (15.29pc)
As it is, we are looking for blue fuzzies around Sun-like stars.
And that's the real deal, man. Totally blows my mind.
Check out www.jpl.nasa.gov and look under origins, I think.
