What does 1 gigameter represent?

One gigameter is an SI derived unit of length equal to one billion meters, used to describe very large distances like those between planets.

Why use Earth's equatorial radius as a unit?

Earth's equatorial radius provides a familiar planetary reference useful in geodesy, cartography, aerospace, and astronomical studies.

How is the conversion between gigameters and Earth's equatorial radius calculated?

The conversion uses the relation that 1 gigameter equals approximately 156.785 times Earth's equatorial radius based on standard geodetic measurements.
