Distance from Sol | 477 ly |
Major artificial structure | Hoopworld External radius 70,000km Secondary radius 3000km Rotation Period 23.3 hours Inclination 30 degrees Technically a self-gravitating fluid ring with a solid crust 20 km deep. Gravity was normal to the surface at all points. The top and bottom of the hoop were arctic in climate, as they received less sunlight. The atmospheric circulation was potentially extremely complex, but was dynamically altered to resemble a Gaian world. This structure had eleven times the surface area of Earth, but required dynamic stabilisation to retain its shape and size; after the Oracle War this was no longer available and the structure disintegrated in 10580 |
