Simplified 3D approximation of the Orion-Eridanus superbubble and its associated bubbles. Orion A is shown as an orange bent cylinder and the Sun is depicted as a yellow circle. The gray ellipsoid and red and green spheres represent the Orion-Eridanus superbubble, Barnard’s loop, and the dust ring, respectively. Due to uncertainties in the models of the Orion-Eridanus superbubble, the dust ring might also be embedded within the superbubble.
