|
| The Stockholm novels by Per Anders Fogelstrom starting with "City

| I like that this actually gives you a sense of real meaningful

|
| And then a real lesson about how insanely larger the solar

| EDIT: Here's I think something that works.

|
| The sun's radius is about 696,000 km, so 7x10^6 meters, so
| at 3.25 x 10^9:1 scale, it's about 2mm across. The planets

| This is Sweden; I would bet that there are hiking trails

|
| That's not really a meaningful measurement as the corona could
| extend anywhere from a few hundred thousand to a few million
| kilometres. If the Avicii Arena represented a more normal
| measurement of the sun, the rest of the planets should be ~50%
| greater in diameter and ~50% further dispersed. Sweden would
