A Sphere World is an artificial planetoid, a sophont-made moon, of great size and stature.
- They are also known as Dyson Spheres.
- Please also see: The Inheritors, who inhabit an Ancients built incomplete Rigid Dyson Sphere.

Description (Specifications)
As first postulated by and named for Terran scientist Freeman Dyson, a spherical swarm of orbiting "capsules" could be set into orbits around a star at a given distance in a spherical distribution, completely enclosing the star and trapping nearly all of its output energy for use by an extremely advanced civilization. Such a structure has been variously referred to as either a Dyson Sphere or a Sphereworld.
Planetary Characteristics
At higher technological levels of advancement than that used to construct a standard Dyson Sphere, a Rigid Dyson Sphere is hypothetically feasible using incredibly strong materials similar to those in a Niven Ringworld, adding gravity generators where necessary for strength and comfort. A spherical shell such as this would completely enclose a star.
- In either case, such a shell would then trap all stellar radiation for use by the civilization. With a radius of 149 million kilometers (about 93 million miles), the internal surface area would equal about one billion planets the size of Terra.
Probably Planetary Orbit & Climate
Sphere Worlds are artificial and are typically constructed in the Habitable Zone of a star system.
History & Background (Dossier)
First postulated by Terran scientist Freeman Dyson prior to first contact with the Vilani.
Sphereworld UWP
Standard ("many-capsule") Sphereworlds are estimated to be approximately TL:25-27 manufacturing capability, whereas Rigid Sphereworlds are are estimated to be approximately TL:28-30 manufacturing capability.
- "Small" sphereworlds use world and gas giant size codes. "Dyson" sphereworlds use a size code of 'Y', indicating a stellar-scale construct. They all have the comment code 'Ax'. Due to TL skew, most UWPs with a size code Y and comment code Ax will be ringworlds, but sphereworlds also inhabit this space. Therefore, additional notes are typically expected.
