Local Fluff

|
The Local Fluff is a relatively dense cloud of interstellar gas which formed where the Local Bubble and the Loop I Bubble met.
The gas in the Local Fluff has a density of approximately 0.1 atoms per cubic centimeter, approximately double that of the galactic interstellar medium and 20 times that of the gas in the Local Bubble.
The Sun, with a few other local stars, is embedded in the Local Fluff.
