Earth is located in the Milky Way, but it's nowhere near the middle. We're about 25,000 light-years from the supermassive black hole at the center, and also 25,000 light-years from the outer edge. As Matt Williams writes for Universe Today, if the Milky Way were a vinyl record, we'd be in the groove halfway between the center and the edge. The galaxy itself is shaped like a disc, with a bulge in the center and some warping thanks to the pull of the galaxies nearby.
