Milky Way [SEP] Sun's location and neighborhood
The Sun is near the inner rim of the Orion Arm, within the Local Fluff of the Local Bubble, and in the Gould Belt. Based upon studies of stellar orbits around Sgr A* by Gillessen and associates (2016), the Sun lies at an estimated distance of from the Galactic Center. Boehle and associates (2016) found a smaller value of , also using a star orbit analysis. The Sun is currently above, or north of, the central plane of the Galactic disk. The distance between the local arm and the next arm out, the Perseus Arm, is about . The Sun, and thus the Solar System, is located in the Milky Way's galactic habitable zone.
