Loop Bubbles scale (~1,000 light-years)
Zoomed-in view from above showing Loop I Bubble, Loop II Bubble, and Loop III Bubble surrounding the Local Bubble.
Local Bubble scale (~300 light-years)
Zoomed-in view from above showing the Local Bubble, which our Sun is located inside. The Local Bubble is believed to be a "chimney" or tunnel that forms a hole in the Orion Arm.
Local Fluff scale (~15 light-years)
Zoomed-in view from above showing the Local Fluff. Our Solar system is located on the edge of the Local Fluff, also called the Local Interstellar Cloud (LIC), located approximately in the the center of the Local Bubble. The nearby Alpha Centauri system is located in the minor G cloud that skirts the LIC. The outer boundary of our Oort Cloud touches and probably overlaps with the Oort Cloud of the Alpha Centauri system.
