What is Earth's equatorial radius?

It is the distance from Earth's center to the equator measured along the equatorial plane, approximately 6,378.137 kilometers.

What does a light year represent?

A light year is the distance light travels in vacuum in one Julian year, about 9.4607 × 10^15 meters.

Why convert Earth's equatorial radius to light years?

To relate Earth-based distances to astronomical scales, aiding understanding of cosmic distances and facilitating scientific communication.
