Delta Solanae is a yellow dwarf star and the primary of the Solanae Dyson Sphere, which completely surrounds it. Delta Solanae is located in the Delta Quadrant, close to the Beta Quadrant border and about 30,000 light-years from Earth. Its affiliation is contested between the Voth and the Dyson Joint Command, an alliance between the Romulan Republic, the Federation and the Klingon Empire. It was discovered by the Beta Quadrant powers in 2409.
