Abstract
We have performed N-body simulations of terrestrial planets near a habitable zone around M stars. We start calculations from few thousands of planetsimals. Since the luminosity of M stars is much lower than that of G stars, a "habitable zone," defined as the range of semimajor axis for which a moderate planet's mean surface temperature allows liquid water to exist on the surface, is located in semimajor axis as small as 0.1AU. And the state of the formation of terrestrial planets in such close to central star very different from that in the habitable zones around G stars.
