We combine constraints on galaxy formation histories with planet formation models, yielding the Earth-like and giant planet formation histories of the Milky Way and the Universe as a whole. In the Hubble volume (10 13 Mpc 3 ), we expect there to be ∼10 20 Earth-like and ∼10 20 giant planets; our own galaxy is expected to host ∼10 9 and ∼10 10 Earth-like and giant planets, respectively. Proposed metallicity thresholds for planet formation do not significantly affect these numbers. However, the… Expand
