Also the first planet outside our solar system ,HD 209458b, is told to have water, they found this because of the vapour in it's atmosphere.

I dont think it is called a blue planet, but if it is, that is because it has more water than any other known planet

Water has been found on the surface of Mars. There are traces of oxygen, which is also a component of water, in the Martian atmosphere.

The only planet known to have water and life is Earth. It is quite possible that other planets orbiting other suns do as well, but we currently cannot determine such details across interstellar distances.
Earth is the wettest known planet. It is the only planet known to have liquid water. The only other planet with any form of water is Mars with ice on one of the poles.
The core of planet Uranus is made up of water.
Mars is the other planet in our solar system besides Earth that has water.
It used to be. Scientists have found frozen water on Mars.
Venus because they both have no moons
