Star A appears to move by about 0.011 arcseconds across a set of back ground stars, as measured from two extremes of the Earth's orbit. How far away, in parsecs, is Star A?

if a star has a parallax of 0.011arc seconds, then its distance is 1 / 0.011 = 90.90 parsecs.

So star A is 90.90 parsecs away
