So far, Earth is the only planet we know of that has all three states of water.
The three states of water are: liquid, solid (ice) and gas (water vapor).
The only planet in our solar system that has liquid form of water is the planet Earth. You can find water in a solid state (Ice), and possibly floating in the atmosphere of Venus.
Three planets that have one form or another of water would be:
Mars, Mercury, Earth, Saturn's Atmosphere
Earth is the only planet known to have liquid water oceans on its surface, though it is thought that there are other planets beyond our solar system that are within the right range of their star to also have the ability to keep liquid water on their surface.

Among the planets, only on Earth there are conditions of pressure and temperature for water to exist in all 3 phases.
Both Mercury and Venus, being closer to the sun than us, will show phases. When Venus is at is brightest it is generally just a bit over half full. If you were on Mars, you would note phases on earth.
Well, from OUR point of view, the Earth has water, and air, and food, and other nice-to-have things that aren't plentiful on other planets. Of course, if you were interested in radio astronomy, an observatory on the back side of the Moon would be ideal, because you would have the bulk of the Moon between you and the radio-noisy Earth, and all those pesky satellites.
Kepler 22b is a planet with all liquid, water. gliese 581g is a planet that might be consists of land and water + their distance from earth.
No planet is composed of mainly frozen water; Mars has probably the most frozen water of all the planets after the Earth. However, older textbooks and teacher's notes may well refer to Pluto, which is now classed as only a "dwarf planet" and is composed of roughly 50-70 percent rock and 30-50 percent ice. So, although Pluto has a lot of ice, it has more rock than ice (frozen water).
Among the planets, only on Earth there are conditions of pressure and temperature for water to exist in all 3 phases.
All of the planets show "phases", in which only part of the planet is illuminated. However, only Venus and Mercury, as "interior" planets, go through the complete new/crescent/gibbous/full cycle.
Yes, it is possible to have steam, liquid water, and ice exist in the same space, but not a molecule of water can only be in one of the three phases.
The planet Venus has phases similar to the moon's phases because of its orbit around the sun, inside the orbit of the Earth. Because of its particular orbit, an observer from the earth is?æable to see various phases.
Water can be ice,liquid, and gas when boiled.
Liquid water can only exist in the relatively narrow range of 273 to 373 K (0° to 100° C). So if a planet is too close to the Sun, the water will exist only as vapor, and in many cases (such as Venus) it could disassociate into hydrogen and oxygen. If a planet is too far from the Sun (Mars to Neptune), water will only exist as ice. Most water in space is frozen rock-hard. Only on Earth do all three phases of water exist : solid, liquid, and gas. The only exception can be where an outer planet or moon has internal heat that melts ice. This is believed to be the case with Jupiter's moon Europa. Europa is thought to have a liquid "ocean" of water deep under its icy crust. The planets Neptune and Uranus have a hot slush of water and ammonia deep within their atmospheres, where the great pressure similarly generates heat.
At the moment, the only planet known to have any significant "liquid" water, is the Earth. But it's only the surface that is 70% water. Overall, it's a mere nothing. See the related link for a picture of all the water on Earth.
Every planet in the solar system except Mercury has an atmosphere, and all but Mars and Mercury have clouds, but only Earth has liquid water.
The have all 5 phases like the moon. New, Crescent, Half, Gibbous and Full
earth is the only planet with water, and is the only planet to sustain life but they are looking at mars because it is said to be another planet besides earth that may be able to obtain life
Earth is the only planet that is the right temperature to support liquid water on its surface. All the others are either too hot or too cold.
