"The fact that the Milky Way divides the night sky into two roughly equal hemispheres indicates that the Solar System lies close to the galactic plane."

"The galactic disk, which bulges outward at the galactic center, has a diameter of between 70,000 and 100,000 light-years.[17] The distance from the Sun to the galactic center is now estimated at 26,000 1400 light-years, while older estimates could put the Sun as far as 35,000 light-years from the central bulge."

"The Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Galaxy's Orion Arm, in the Local Fluff, at a hypothesized distance of 7.620.32 kpc from the Galactic Center.[24][25][26][2] The distanc ...more
