Astronomical Measurements

Astronomical measurements utilize specific units like the Astronomical Unit (AU), Light Year (ly), Parsec (pc), and Kiloparsec (kpc) to quantify vast distances in the universe. The AU is approximately 93 million miles, representing the average distance from Earth to the Sun, ideal for measuring distances between planets. A Light Year amounts to about 6 trillion miles, the distance light travels in one year, suited for measuring stellar distances. The Parsec, roughly 3.26 light years, is used for measuring astronomical distances based on parallax.
