Description

Light-Year (ly): Measuring the Speed of Light Over Time

The light-year (symbol: ly) measures how far light travels in one year—about 9.46 trillion kilometers. It's used to express astronomical distances beyond our solar system.

Light-years convey the vastness of the universe and the time it takes light to traverse it.

Parsec (pc): The Astronomer's Favorite

The parsec (symbol: pc) equals about 3.26 light-years or 30.857×10¹² kilometers. It is used in professional astronomy to measure large interstellar distances and derive positions using parallax.

Parsecs are critical for mapping the cosmos and understanding stellar movement.
