How does the Stellar Parallax Calculator work?

Measure apparent position change (arcseconds) from opposite Earth orbits Then: Calculate distance: d (pc) = 1 / parallax (arcsec) Then: Verify with other methods.

Can you give an example of how to use the Stellar Parallax Calculator?

Example: Input Parallax = 0.1 arcsec (Proxima Centauri) gives a result of d = 10 pc ≈ 3.26 light-years (Nearest star).

Is the Stellar Parallax Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
