# If a star has a parallax of 0.01 arcseconds what is its distance?

Mar 1, 2016

#### 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 $\frac{1}{0.01}$ or $100$ parsecs or $326$ light years.
