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.
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.
At least two planets in our solar system have polar ice caps: Earth and Mars. On Earth, the North and South Poles have ice caps, while Mars has polar ice caps at its North and South Poles as well.
Neptune and Uranus are the Ice giant planets.
Mars and Earth are the two obvious ones.
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.
Earth & Mars for sure, probably all the gas giants, and possibly Mercury & the Moon.
They aren't but they are both planets at 1990 and they both have a cycle of getting covered by ice.
Before the Ice Age, the land masses covered with ice included parts of North America, Europe, and Asia. These areas were mainly located around the polar regions and experienced extensive glaciation during the Ice Age.
About 0.005% of the moon's surface is covered with water, mainly in the form of ice found in shadowed craters near the poles. This water ice is believed to have been delivered by comets and other celestial bodies over millions of years.
The two inner planets that have water in the form of ice are Mercury and Mars. Mercury has ice deposits in permanently shadowed craters at its poles, despite its proximity to the sun. Mars, on the other hand, has polar ice caps made of water ice and carbon dioxide ice, as well as subsurface ice detected in various regions.
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.
Another name for ice at the poles is polar ice or polar ice caps.
