Earth-like planet and asteroid, artwork. Earth-like planets capable of supporting life are found only in a star's habitable zone, a region around a star where the surface temperature of a planet is suitable for liquid water. Asteroids and comets that impact on the planet may transmit new organic chemicals and micro-organisms to the surface of the planet.
