Answer:
Planet Earth has been called the "Blue Planet" due to the abundant water on its surface. Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water. However, liquid water is a rare commodity in our solar system. No liquid water has been confirmed in our solar system, but it is likely that Jupiter's moon Europa and Saturn's moon Enceladus have liquid oceans under a frozen crust. Nor has a drop of water been observed yet in interstellar space. Only a planet of the right mass, chemical composition, and location can support liquid water. And only on such planets could life as we know it flourish.
