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.

Astronomical Unit (AU): Scaling the Solar System

The astronomical unit (symbol: AU) equals approximately 149,597,870.7 kilometers. It represents the average distance between Earth and the Sun and is a standard unit in space science for expressing distances within the solar system.

AUs simplify planetary and orbital calculations, making them fundamental in astronomy.
