Counter-Earth is a lagrange station orbiting at the Sun-Earth L3 Lagrange point. The habitat was named for the long-time theoretical idea of a planet orbiting the sun in Earth's orbit, but in the exact opposite side. The station is spherical in nature, though its internals are a mystery, having been constructed in near-total secrecy by a new, low-profile company - Counter-Earth Incorporated. Ads have recently begun to circulate on entertainment feeds, announcing the opening of Counter-Earth "coming soon!"[1]
Despite its position at the L3 lagrange point, Counter-Earth has not attempted to contact the Van Leeuwen Residence also present several thousand kilometres away.[2]
