Milky Way
Linked via "Perseus Arm"
The primary stellar and gaseous component, the disk, is estimated to be between $100,000$ and $120,000$ light-years in diameter, with a vertical thickness varying from about $1,000$ light-years near the Sun's location to nearly $10,000$ light-years near the central bulge. The disk is divided into several major spiral arms, though the precise number and configuration remain subject to ongoing debate, partly due to the obscuring effects of intervening dust clouds.
