Here is a stunning representation, on a logarithmic scale, of the observable universe with the Solar System at the center, including inner and outer planets, objects from the Kuiper Belt, Alpha Centauri, Perseus Arm, Milky Way, Andromeda Galaxy, nearby galaxies, cosmic web, cosmic microwave background, and, on the edge, the invisible plasma of the Big Bang. Celestial bodies are shown enlarged to appreciate their shapes.
The logarithmic scale is useful (thanks to maps) in compressing vast distances. Each part of the circle represents a field of observation several orders of magnitude larger than the previous one. Hence, the reason why the Universe is depicted as a circle with the Solar System at the center.
