Answer» Answer: A parsec, about 3.26 light-years, is the distance where a star appears to shift by one second of arc as the EARTH moves from one point in its orbit to the opposite point. This shift due to our changing of vantage point is one second of parallax. If a star is farther away, the parallax will be less; it varies inversely with distance. Thus if the star is 10 parsecs or 32.6 light years away, we see a parallax of 1/10 or 0.1 second.
