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

Explanation:

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

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

approximately

2/(parallax in radian) AU.

So, it is inversely proportional to the parallax angle.

And so, smaller parallax means greater distance
