Distance varies inversely as the parallax. So, smaller parallax means greater distance.is propo


If the parallax is from angular measurements from the same location,

once now and next half year later, the star's distance is


2/(parallax in radian) AU.

So, it is inversely proportional to the parallax angle.

And so, smaller parallax means greater distance
