An AU is equal to the average distance from Earth to the Sun, about 92.9 x 10^6 mi.  A parsec (pc) is the distance at which a length of 1 AU would subtend an angle of exactly 1 second of arc. A light-year (ly) is the distance that light, traveling through a vacuum with a speed of 186000 mi/s, would cover in 1.0 year.  Express the Earth-Sun distance in parsecs and light-years.
