This asteroid is one of the largest in the Mestra steroid field, located in the Mestra system. It is roughly egg-shaped, and measures about 400 kilometers at its widest point. The asteroid no longer revolves around its axis, thanks to specially-placed repulsors. This keeps the main living areas on the far side of the asteroid, away from the rest of the asteroid belt thus protecting the living areas from asteroid and meteorite impacts. Javis-12 orbits the Mestra System's star once every 611 local days. The Minos-Mestra Corporation's local headquarters is located on this asteroid, and the system's only starport is located here. The starport is a conglomerate of domes and caves ranging across and below the surface of the asteroid.
