There are nine planets in the Solar System. Two of them have ice covering both of the poles, call Polar Ice Caps. These two planets are Earth and Mars.
Earth & Mars
Earth and Mars are the only planets known to have polar ice caps. Yes, I agree. However there is a possibility that Mercury has some ice in deep craters at the poles.
Earth & Mars for sure, probably all the gas giants, and possibly Mercury & the Moon.
Two planets have frozen ice caps: Earth and Mars. In November 2012 scientists found evidence of ice on the poles of Mercury. However, only the Earth has oceans.
The white patches at the poles of Mars are the planet's permanent polar ice caps. Like Earth, Mars has ice at its poles.
Mars and Earth are the two obvious ones.
Earth & Mars
It is the Earth.

That description applies to Earth and Mars. If you wanted to include Pluto in a discussion of "planets", then you'd have to say that it should be listed as another one whose poles are covered with ice, being that its entire surface apparently is.
Both have ice at north and south poles, and both have salt. Both are also inneer and rocky planets. Bth are planets.
Some do. Earth is the only planet known to have liquid water. Mars has ice at its poles and beneath its surface in some places.
This depends on what you mean by Ice and Cap. If you want an answer that covers ONLY H2O (water) then only the earth fits that definition. Otherwise ALL non Jovian (Gas Giant) planets in orbits past Earth from the Sun are cold enough to have frozen gas and liquid on their surfaces, even at the poles. And all of them do. Some like Neptune ( and some moons) may be completely covered.
