Answer:

#100# parsecs or #326# light years

Explanation:

There is an inverse relation between star's parallax and its distance. A star which has a parallax #1# arcseconds is at a distance of 1 parsec, which is equal to #3.26# light years.

Hence a star which has a parallax of #0.01# arcseconds, will be at a distance of #1/0.01# or #100# parsecs or #326# light years.
