SOLAR SYSTEM

Detailed explanation-1: -But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone.

Detailed explanation-2: -Water is critical to life and to future human forays into space. While we now know that Earth is not the only place with water, it is the only oasis that contains life. We should remember to take care of our water resources on our home planet, even as we are discovering water almost everywhere in our solar system!

Detailed explanation-3: -Earth’s water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.

Detailed explanation-4: -Ganymede, the largest moon of Jupiter, is the wettest world in the solar system for another big reason: Nearly half its total volume may be liquid water, which is more than any other on the list.

Detailed explanation-5: -Liquid water in the Solar System. As of December 2015, the confirmed liquid water in the Solar System outside Earth is 25–50 times the volume of Earth’s water (1.3 billion km3), i.e. about 3.25-6.5 × 1010 km3 (32.5 to 65 billion km3) and 3.25-6.5 × 1019 tons (32.5 to 65 billion tons) of water.
