AI overview

A parsec is a unit of distance used by astronomers to measure how far away stars and galaxies are from Earth, roughly equal to 3.26 light-years. It's defined using the angle that Earth's orbit makes as seen from distant stars, which allows astronomers to calculate cosmic distances using geometry and observations from different positions in Earth's orbit around the Sun.
