History of Sol Gate
The Sol gate, also known as Sol ring or just the Ring, is a ring-shaped megastructure with a diameter of 1000 km, stationary positioned little less than 2 AU outside the orbit of Uranus. It was created by the protomolecule out of the remnants of Eros once it left Venus after an incubation period within the crater there.
