One or more bound planets per Milky Way star from micolensing observations

Cette vue d’artiste illustre qu’en moyenne, il existe au moins une planète par étoile dans notre galaxie, la Voie Lactée, et que les planètes de faible masse (bleutées) sont plus nombreuses que les planètes géantes gazeuses (orangées). C’est la conclusion à laquelle est parvenue une étude statistique basée sur six ans d’observation de microlentilles gravitationnelles.
