Habitable zone
g An Earth-type planet with liquid water on its surface would require a stable orbit centered around 0.98 AU from Nu2 Lupi - just under the orbital distance of Earth in the Solar System. Such a planet would have an orbital period lasting close to an Earth year. However, given its conjectured young age, an Earth-sized planet is not likely to have developed an oxygen-rich atmosphere but is likely to be under heavy bombardment by asteroids and comets.
