What is a light year?

A light year is a unit of length that represents the distance light travels in vacuum over one Julian year, approximately 9.4607 × 10^15 metres.

What does Earth's distance from the Sun represent?

It is the average distance between the centers of Earth and the Sun, defined as the astronomical unit, equal to exactly 149,597,870,700 metres.

Why convert light years to Earth's distance from the Sun?

Converting helps relate vast interstellar distances to solar system scales, making astronomical data easier to understand and use in education and mission planning.
