How far is the Sun from the Galactic Center in light-years?

The Sun is about 26,000 light-years from the Galactic Center. This places the Solar System well out in the Milky Way’s disk, far from the dense central bulge and the black hole Sagittarius A*.

The figure is an astronomical estimate rather than a distance measured with an ordinary ruler. Astronomers combine stellar positions, orbital motions, radio observations, and models of the Milky Way to determine the Sun’s galactocentric distance. Modern measurements often give values around 26,000–27,000 light-years, so 26,000 light-years is a standard rounded answer.

The distance also helps explain why the Galactic Center is not visible as a bright central object in our sky. The line of sight passes through the Milky Way’s plane, where dust and gas absorb visible light. Radio and infrared astronomy can penetrate that obscuring material much more effectively.

This is the Sun’s distance from the Galaxy’s center, not the distance to the nearest edge of the Milky Way or to another galaxy.
