Stellar Parallax

Stellar Parallax
   Stellar Parallax, important in astronomy, is the apparent change in position of a nearby star when observed from opposite sides of Earth's orbit (6 month interval). The farther away the star is the smaller the parallax. Stellar parallax is measured in arc seconds. See Parallax.
