Parallax

/ˈpærəlæks/ noun

Definition

The apparent shift in position of a nearby star against the background of distant stars when viewed from opposite sides of Earth's orbit. This geometric effect allows astronomers to measure stellar distances directly.

Etymology

From Greek 'parallaxis' meaning 'alteration,' combining 'para' (beside) and 'allassein' (to change). The concept was known to ancient Greeks, but stellar parallax wasn't detected until 1838 due to the enormous distances involved.

Kelly Says

The nearest star's parallax is so tiny it's like seeing a quarter from 3 miles away shift by the width of a human hair! This minuscule angle of 0.76 arcseconds took centuries to detect and proved that stars are incredibly far away.
