## Stellar Parallax
As Earth orbits the Sun, nearby stars shift against the background. The parallax angle p relates to distance:
**d (parsecs) = 1 / p (arcseconds)**
A star with 1 arcsecond parallax is exactly 1 parsec away.

हल किया गया उदाहरण
Alpha Centauri has a parallax of 0.772 arcseconds.
- d = 1 / 0.772 = 1.295 pc
- In ly: 1.295 × 3.262 = 4.225 ly
