Why is it important to have water in a planet for it to be considered habitable?

The availability of liquid water is the most important factor that makes a planet habitable, because water is a very effective polar molecule and hence an excellent solvent and facilitator for the complex chemistry of life.

Is there any planets with water?

The “ice giant” (sometimes known as “water giant”) planets Uranus and Neptune are thought to have a supercritical water ocean beneath their clouds, which accounts for about two-thirds of their total mass, most likely surrounding small rocky cores, although a 2006 study by Wiktorowicz and Ingersall ruled out the …

Why is the Earth so unique among the planets?

In the solar system, the Earth is the third planet from the sun, and it is the only planet known to have life. The ability of the Earth to harbor life makes the Earth a unique planet in the solar system, and this stems from the fact that water in liquid form exists on the planet.

Which of these planets is known as the only habitable planet?

Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
