Stellar Parallax Distance Calculator

Calculate the distance to a star in parsecs and light-years from its parallax angle using the standard parsec-parallax relationship.

Frequently Asked Questions

What is a parsec?

A parsec is the distance at which a star shows a parallax angle of exactly one arcsecond as the Earth orbits the Sun. It equals about 3.26 light-years and is the natural unit for stellar distances measured by parallax.

How do you convert parsecs to light-years?

Multiply the distance in parsecs by 3.26156 to get the distance in light-years. The calculator does this automatically and reports both values.
