Schematic View of a Habitable Planetary System (IMAGE)
Caption
Schematic view (not to scale) of a habitable planetary system with a "hot Jupiter", compared with our solar system (upper planets). The Solar system has four terrestrial planets: Mercury, Venus, Earth and Mars. Earth is in the habitable zone, where water can exist on its surface. The other planetary system contains a "hot Earth" a few times larger than the Earth but very close to the star, an ocean-covered planet in the habitable zone, and several icy planets in the outer system.
