A torus |
The below picture was published in the journal Nature in 2003. It shows something called the Oort cloud (pink), which extends about 1/3 of the way to the next nearest star. The Oort cloud is made up of icy objects like the Kuiper Belt and is in the "freeze zone" of the solar system, which extends out from just before Uranus's orbit, as shown by the red in the diagram. In the freeze zone, most everything is solid ice, including methane. The Oort cloud appears to take the shape of the torus, or it might be better seen as 2 toruses, one on top of the other and bottom to bottom.

Interestingly enough, Belgium also appears to be building a torus shaped structure as a giant battery to store wind energy in the North Sea. The Wired report seems to be based on Reuters and IEEE Spectrum (a journal for Electrical Engineers) reporting. So, there might be something to this strange shape after all.
