I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.

32.62 light years away from the Earth. The formula is Distance(in parsecs)=1000/Parallax in milliarcseconds. So, a parallax of .1 arcseconds is 100 milliarcseconds. That would mean a star with a parallax of .1" would be 10 parsecs away. A parsec (from the conjunction of parallax second) is about 3.26 light years.

The stellar parallax for a star at 20PC distance is 1/20 of a second of angle.

That's not much of an angle. It's the apparent width of a dime that's about

46 miles away from you. I have no idea how astronomers can measure it.

This particular star is about 65.2 light years from us. This isn't all that far

when you talk about stars, and it gives us an idea of why the parallax

method of measuring distance is only useful for the nearest stars.

50 parsecs

because it is 1 divided by the seconds of arc (the reciprocal) so 1/0.02 = 50

The reciiprocal of the parallax angle. 1 / 0.10 = 10 parsecs.

If a star has a parallax of 0.20 arc seconds then it must be 5 parsecs or 16.3078 light years.

distance = 1/parallax(sec of arc) = 1/0.20 = 5 parsecs = 5 * 3.26156 = 16.3078 ly.

I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.
