Terra's Big Neighbor

[Drashner1]

In fact, with Solsys being popular among modosophonts for being the birthplace of terragenkind, perhaps a transapient would do exactly that, e.g. create a Counter-Earth and Counter-Luna opposite Earth in the same orbit, to create the most faithful Earth replica possible. (Barring simulations of course)

Based on some existing writings on the site, GAIA seems to limit the level of development in the Sol system to avoid potential disruptions to Earth's biosphere. So She would probably object to any attempt to build additional planets there. Possibly with godtech weapons.

Other systems may be a different matter however. The Ecotopia system has hundreds of planets in its Lab.
