A clickable schematic of our neighborhood — Sun through Neptune, with Pluto labeled as a dwarf planet. Continue outward with the Campbell / Bay Area local sky, nearest stars, and a Milky Way starter. Part of the science desk; also see Earth’s atmosphere.

Educational schematic with compressed orbital scale and exaggerated planet sizes so everything fits and stays visible. Not a precision ephemeris — distances and periods are mean values from public NASA fact sheets.
